# Gautam Biswas

Gautam Biswas (Bengali: গৌতম বিশ্বাস; born 23 May 1956) is an Academic serving as a Senior Professor Emeritus in Mechanical Engineering at BITS Pilani, K. K. Birla Goa Campus from January 2025. Earlier, Prof. Biswas served as the director of Indian Institute of Technology (IIT) Guwahati, and director of the CSIR - Central Mechanical Engineering Research Institute at Durgapur. He was the G.D. and V.M. Mehta Endowed Chair Professor, and Dean of Academic Affairs at IIT Kanpur. His total tenure in various capacities at the Indian Institute of Technology Kanpur lasted from 1990 to 2024.

## Education

Biswas completed his B.E. from IIEST (formerly B.E. College under Calcutta University) in 1979 and his PhD from the Indian Institute of Technology Kharagpur in 1985. He was a 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), the Indian Academy of Sciences (IAS, Bangalore), and the National Academy of Sciences India (NASI, Allahabad). He is also a Fellow of the Indian National Academy of Engineering (INAE) and the Institution of Engineers (IEI).

## Research

Biswas has contributed to the fields of heat transfer and fluid mechanics. His work on enhancing heat transfer using delta-winglet type vortex generators has been included in international textbooks. The concept has been used by industry for various HAVC systems. Additionally, he has contributed to the understanding of bluff body flows. His work on large-eddy simulation of flow past bluff bodies and heat transfer in impinging jets has been noted in the scientific community. Biswas's contributions pertaining to handling free surface flows and some of his investigations related to the prediction of bubble growth in film boiling have been recognized. Biswas and co-researchers analyzed the impact of falling drops on a liquid surface and contributed to the understanding of 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 interest. His group probed the zone of large bubble entrapment and underlying physics. He has published on the formation of air bubbles from a submerged orifice. His group analyzed the impact of a train of high-speed micro-drops on a deep liquid pool and explained a mechanistic route leading to the creation of a deep cavity inside the liquid pool. Biswas and co-researchers contributed to understanding that EMT cells are more drug-resistant, with a two-fold higher expression of the multi-drug resistance (MDR1) gene.
