Conduction and Convection: Fundamentals and Applications

By Prof. Gautam Biswas, Prof. Sameer Khandekar   |   IIT Kanpur, IIT Kanpur
Learners enrolled: 560
This is the first introductory course on heat transfer and will be useful for undergraduates as well as graduate level students. In the first part of the course, the focus is on analytical treatment of the subject wherein the thermal transport phenomena by conduction and convection modes are delineated under different conditions which are encountered in engineering practice. Analytical solutions of the governing equations are presented with sufficient rigour and depth. The course also introduces phase-change heat transfer, i.e., boiling and condensation. The later part of the course deals with engineering applications, with a focus on understanding conventional industrial heat exchangers and passive heat pipes and thermosyphons.

Instructor bio

Prof. Gautam Biswas

IIT Kanpur
Dr. Gautam Biswas is presently a Professor of Mechanical Engineering at the Indian Institute of Technology 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. He was the G.D. and V.M. Mehta Endowed Chair Professor, and Dean of academic affairs at IIT Kanpur. The research group of Professor Biswas at IIT Kanpur identified the phenomenon of Rayleigh-Taylor Instability during the bubble formation in film boiling. This was a significant addition to the classical theory, based on Taylor Helmholtz instability. Another seminal contribution of his group is identification of zone of large bubble entrapment and underlying physics during the complete coalescence of a falling drop on a liquid surface. Professor Biswas is the author of more than 150 publications in the International Journals. He has completed guidance of 23 PhD theses.He was a Humboldt Fellow in Germany in 1987-88 and JSPS invited fellow in Japan 1994. He is a Fellow of the American Society of Mechanical Engineers (ASME). He has served a full term as the Associate Editor of the Journal of Heat Transfer (Trans ASME). He was a Guest Professor at the University of Erlangen-Nuremberg in 2002. Currently he is Associate Editor of a well-known CFD-Journal, - Computer and Fluids.Prof Gautam Biswas is a Fellow of the all three major Science Academies of India, such as, 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 a Fellow of the Indian National Academy of Engineering (INAE) and Institution of Engineers India (IEI). He has been awarded the esteemed J.C. Bose National Fellowship by the Department of Science and Technology, New Delhi in 2011. Prof. Biswas was bestowed with Distinguished Alumnus Award by BESU (now IIEST, Shibpur) in the year 2013.
