Gautam Biswas (Bengali: গৌতম বিশ্বাস; born 23 May 1956) is a professor of mechanical engineering at the Indian Institute of Technology (IIT) Kanpur. Earlier, he has been the director of Indian Institute of Technology Guwahati, and director of the CSIR - Central Mechanical Engineering Research Institute at Durgapur.[1] As a faculty member of IIT Kanpur, he has served the Institute in various capacities including the Dean of Academic Affairs.[2]

## Education[edit]

Biswas completed his B.E. from IIEST (Erstwhile B.E. College under Calcutta University) in 1979. He completed his PhD from the Indian Institute of Technology Kharagpur in 1985. He was an Alexander von Humboldt Fellow at the Ruhr University Bochum in Germany and JSPS Invitation Fellow at the Yokohama National University, Japan. Biswas is a Fellow of the Indian National Science Academy (INSA, New Delhi),[3] the Indian Academy of Sciences (IAS, Bangalore) and the National Academy of Sciences India (NASI, Allahabad). He is a Fellow of the Indian National Academy of Engineering (INAE) and Institution of Engineers (IEI).

## Research[edit]

Biswas has made contributions in the areas of heat transfer and fluid mechanics. His work on enhancement of heat transfer using delta-winglet type vortex generators is a major contribution[4][5] which is included in the advanced international text books.[6] The innovative concept has been used by the Industry for various HAVC systems. Furthermore, he has contributed significantly in understanding the bluff body flows.[7] His work on large-eddy simulation of flow past bluff bodies[8] and heat transfer in impinging jets[9] have been deeply admired by the scientific community. Contributions of Prof. Biswas pertaining to handling free surface flows[10] and some of his investigations related to prediction of bubble growth in film boiling[11][12][13] are considered to be path-breaking. Prof. Biswas and co-researchers analyzed impact of falling drops on a liquid surface[14][15] and made fundamental contributions to the body of knowledge related to partial coalescence and the transition between coalescence and splashing. Experimental evidence of large bubble entrapment occurring outside the traditional small region on the V-D map, made the boundary of large bubble entrapment a topic of greater importance. A seminal contribution of his group probes the zone of large bubble entrapment and underlying physics.[16] He has made significant impact through his publications on formation of air bubbles from a submerged orifice.[17][18] His group analyzed the impact of a train of high-speed microdrops on a deep liquid pool. The work explained mechanistic route leading to creation of a deep cavity inside the liquid pool.[19] Prof. Biswas and the co-researchers contributed in understanding that the EMT cells are more drug resistant with a concomitant two-fold higher expression of the multi-drug resistance (MDR1) gene.[20]

## Awards[edit]

* Biswas was awarded an honorary doctorate by the National Institute of Technology Agartala in 2017.
* He has been conferred honorary doctorate by the Aristotle University of Thessaloniki, Greece, in 2018.[21]
* IIT Kanpur bestowed upon Biswas the award of Institute Fellow for the year 2020.[22]
* In recognition of his outstanding contribution to teaching, IIT Kanpur conferred the Distinguished Teacher Award upon Biswas in 2022.[23]
* Biswas has received the 2023 ASME Heat Transfer Memorial Award in the Science Category for Sustained and Outstanding Contributions to Thermal Science and Engineering, including Heat Transfer Enhancement, Phase Change Heat Transfer with and without Electrohydrodynamic Forces and Dynamics of Liquid Jet and Droplet Impingement.[24]Biswas receiving the ASME Heat Transfer Memorial Award on October 31, 2023 at the Convention Center, New Orleans, USA
* In 2011, he was awarded the J C Bose National Fellowship by the Science and Engineering Research Board (DST), Government of India.[25]
