Education

Biswas completed his B.E. from IIEST in 1979 and his PhD from the Indian Institute of Technology Kharagpur in 1985. He was a at the Ruhr University Bochum in Germany and at the Yokohama National University, Japan. Biswas is a Fellow of the Indian National Science Academy, the Indian Academy of Sciences, and the National Academy of Sciences India. He is also a Fellow of the Indian National Academy of Engineering and the Institution of Engineers.

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 investigations on proper orthogonal decomposition to analyse coherent structures in turbulent flows and large-eddy simulation of flow and heat transfer in impinging jets have been admired by 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 gene.
