Exploring EHD

  • Contributor: Prof. Anandaroop Bhattacharya, Dept. of Mechanical Engineering, IIT Kharagpur

The last week of November saw sixteen eminent researchers from leading universities in France and India congregate at IIT Kharagpur to join four of our own colleagues with a common objective of knowledge sharing and what followed was three days of “fluid” interactions and “charged up” ideas among this “microcosm” of professionals from mechanical, chemical, electrical engineering, applied physics and medical science disciplines. This Indo-French workshop on “Recent Advances in ElectroHydroDynamics (EHD) – applications in microfluidics” was organized at IIT Kharagpur during 27-29 November 2019.

About ElectroHydroDynamics (EHD)

AC Electrothermal Flows for cooling applications

EHD, strictly speaking, is a scientific domain studying all the phenomena resulting from interactions between Electricity and Hydrodynamics and governed by Naviers-Stokes and Maxwell equations (neglecting any magnetic effects)[1]. With its fundamental and industrial applications, EHD becomes a truly multidisciplinary area that brings together research expertise from various fields including electrical engineering, physics, aerodynamics, materials, electrochemistry, biotechnology, geology, medical sciences and heat transfer.

The discovery of EHD phenomenon goes back to the days of Faraday. However, the advances in the field were rather slow for more than a century. The field got a boost in the seventies with the advances made in

  1. computer and numerical simulation techniques and
  2. new technologies for the realization of more and more complex
    experiments.

Since the 1990s, with the advent of microsystems and microfluidics, EHD has witnessed a rapid rise in its developments both in fundamental studies and applications. Advances in electrostatics, electrospray, electrowetting, electrokinetics including electro-osmosis and electrothermal flows have subsequently come from numerous research groups across the world.

About the Workshop

The Indo-French workshop at IIT Kharagpur brought together dynamic researchers working in different facets of EHD and/or in Microfluidics where they presented and shared their own research work with an objective to identify synergies and explore avenues for new innovations at the intersection of disciplines. The workshop was made possible through funding from the Indo-French Centre for the Promotion of Advanced Research (IFCPAR/CEFIPRA), a bilateral organisation set up by Government of India and Government of France to promote international collaborative research in advanced areas of Science &Technology.

The first two days of the workshop witnessed technical presentations of the highest quality and encompassing the two broad themes of droplet dynamics and electro-kinetic flows and covering advances in fundamental understanding as well as applications in a multitude of domains including flow control, EHD pumping, micromixers, flow atomization, medical sciences, pollution control, electronic cooling and earth sciences.

A third of the IIT KGP freshman community certainly had an exceptional experience this winter. The annual National Service Scheme (NSS) camp for this year was based at village Shyameshwarpur under Gopali Gram Panchayat of Kharagpur Block I. Activities were also carried out at neighbouring villages, Sholadahar and Nachna. A total of 553 first-year students participated in this one-week long camp that started on 28th November.

Having to arrive by 7 a.m. at the campsite and stay on till past 4 p.m., the volunteers initially had an arduous time. “The first day was really difficult,” Saurabh Mishra, studying at the Dept. of Civil Engineering, from Allahabad confessed. “But as the days progressed, I was surprised that I had started enjoying the camp entirely”.

The first day of the camp witnessed a rally through the village, intended to raise awareness on common social issues via posters, created by the students themselves. A workshop on the principles of First-Aid and the basic know-how of dealing with accidents was conducted on the following day. The next few days were dedicated to advisory and guidance sessions for the volunteers. “The talk on stress management has really changed me,” one camper remarked. “I am very optimistic about the next semester”.

From a pre-camp need-based survey, two villages were identified for cloth distribution and conducting a medical camp for the needy. Old clothes, collected by volunteers from houses within the institute campus a few weeks prior, were distributed freely to approximately 250 villagers of Sholadahar and Nachna. A medical camp was held at Sholadahar, where more than fifty villagers received treatment for free by a team of qualified doctors. The prescribed medicines were also given away free of cost.

In Shyameshwarpur, a team of students worked on clearing a 300-meter stretch of kaccha road, which was impassable due to overgrown thickets and bushes. A villager was pleased about the work completed near her house. “The work is much better than what even paid workers could have done,” she commented in Bengali.

Many students worked on creating much-needed drainage systems within the village. “The work was hard, but we are thoroughly satisfied,” Supreeta Sen, from the Dept. of Chemistry said, grinning. “This place was very rugged and rocky. But it was worth it”. Her team had successfully dug two-feet-deep channels providing drainage to several blocks of houses. Other teams worked on other parts of the village.

The village panchayat identified a parcel of land to develop fruit orchard. The otherwise barren land was of the size of three football grounds. A few teams worked there to do the groundwork for plantation. They dug ground at specified distances, cleared bushes and weeds and made the field ready. This orchard is expected to generate more income for the village. Another team dug deeper into an existing pond aiming to harvest rainwater better.

A street play session, fondly titled the Nukkad Natak, was conducted on the fourth day, addressing the grave social issues that are still found lurking in a modern era. From writing script to conducting the rehearsal and finally, performing the play in front of all was a challenge as most never acted in any play before. The quick learner they are, each team performed well and admits that this was one of the most memorable experiences of the camp.

The counseling centre, IIT Kharagpur, held a talk on substance abuse. Members from St. John Ambulance used mannequins to demonstrate the First-Aid and CPR principles in the camp. Dr. T. K. Bhunia, an Ophthalmologist at Kharagpur sub-divisional government hospital, also addressed the volunteers briefly.

The camp has led to IIT students from all walks of life, all from distant corners of the nation, to come together and volunteer to help the underprivileged. “Our purpose in holding the camp is to make our students aware of the realities of life in rural India,” said Prof. Arghya Deb, Program Coordinator of NSS IIT Kharagpur, when asked for his perspective on the camp. “When I see the enthusiasm with which most of the campers have approached their allotted tasks, I think we have to a large extent achieved this goal.”

While sharing camp experience campers talked about how the camp helped them to connect to India that was largely unknown to them. Now, they can empathize better with the vast majority who are disadvantaged on many counts. Working for a cause and in a backdrop like this helped them develop a rich bonding with fellow students.

Writing camp diary was a part of the daily exercise in this camp. Navonil Natta Barman, a Mechanical Engineering student hailing from North Bengal writes, “The penultimate day of the camp began with the excitement of being able to go home soon. While we were working, we were asked to share our experience at the NSS camp. We all gathered and began to share our experiences. The leaders stated how NSS has brushed their leadership skills. Everyone put forward various aspects but one thing was globally accepted, i.e. the NSS gave us a new family. Although I knew we were all going to meet again in a month’s time, I was emotional for a while.”

The regular activities of NSS IIT Kharagpur comprise of weekly three hours of work in twenty villages and slums of our neighbourhood.

 

Lessons from Day 3

Beating all conventional logic, which would expect the number of placements to go down steadily with each passing day, the figures at IIT Kharagpur show a consistently upward trend. From 170 placements offered on Day 1, the figure went up to 250 on Day 2. A total of 162 were placed on Day 3, with the top recruiters of the day being Honeywell, Axis Bank, ANI Technologies (OLA) with 34, 12 and 10 offers respectively.

Perhaps the faces said it all. Although still clad in their crisp white shirt and dark trousers and coat, many of those assembling in Nalanda bore little or no mark of the tension that had surfaced on faces on Day 1. Some of them who had been placed were still gambolling around Nalanda, if only to pep up their friends.

Amul Patwa from the Mathematics Department had got his placement in AppDynamics – an application performance management and IT operations analytics company based in San Francisco – on Day 1 itself but was still hanging around in Nalanda to cheer up his friends. So was Soumoshree Saha from the Industrial and Systems Engineering Department, who had got placed in Flipkart on Day 2.

“All things seemed to be going wrong on the first day for me, but things went smoothly on Day 2 and I got my placement by forenoon itself,” said Soumoshree.

Software was still dominating the offers, said an official from the Career Development Centre of IIT Kharagpur, but offers were robust from the core, analytics and financial and consulting sectors as well. In fact, there have been a substantial number of placements in the banking industry. The number of offers from public sector units had also gone up by three-fourths.

The biggest surprise of this year’s placements has been the number of offers from international firms, with the Japanese companies dominating the show with as many as 24 offers so far.

“What is undoubted is the preference for coding skills. In today’s world, the mantra is coding, so if students are well-equipped in coding, they have an obvious advantage,” said Prof. G.P. Raja Sekhar, Chairman, Career Development Centre, IIT Kharagpur and Chairman, All India Placement Committee.

The fact that stood out as the most obvious conclusion during the placement rounds at Nalanda was that irrespective of the department one belonged to, anyone with a good CGPA had a good chance of securing a placement. This is a fact that IIT Kharagpur has always tried to impress upon JEE qualified students during counselling, when the choice of department becomes an enormous dilemma for both students and their families.

The other fact was the skills that students need to pick up before they face placement. Take the case of Ashutosh Bhaskar from the Geology and Geophysics Department. Ashutosh has got his placement at Tiger Analytics, an advanced analytics and AI consulting company. “I not only cleared several certification courses in analytics, but also sought out internships in places where I could use and improve my analytics skills,” said Ashutosh. “Yes, the booming thing today is data analytics,” concurred Soumoshree. So did Manpreet Gulia from Chemical Engineering, who had secured her placement with Barclays.

Sometimes the curriculum itself at IIT Kharagpur prepares the student for the required skills. Soumoshree said, “My curriculum at the Industrial and System Engineering was diverse and I picked up the necessary skills in data and optimization analytics as also in supply chain management.” The student can also opt to pick up these skills through the curriculum. Take Krutarth Satoskar, who while doing his graduation in Biotechnology and Biochemical Engineering also did his minor in Financial Engineering. Not surprisingly, Krutarth has secured his placement in JP Morgan.

Together with the technical skills, the soft skills are as important. Parimal Pratyush of the Industrial and Systems Engineering reminded his interviewer of their significance while hurrying for his session on Day 2 of the placement. He recalled that both the Students’ Welfare Group, a student body operating under the Dean, Student Affairs, and Communiqué, the ‘Official Soft Skills Society’ of IIT Kharagpur have run exclusive sessions to groom students for the placement season. Communiqué, which started in 2006, with the aim to provide students a strong platform to improve their soft skills and personality, conducted a bootcamp and language improvement workshops this year. The society also launched ‘Finshots’ or newsletters they sent out to students in association with ‘Finception’, an IIM-A alumni Startup, to cover important financial and business news.
