    The Chemical Engineering Department would like to welcome Aniruddha Pandit from ICT Mumbai

    Heating the food items to the required temperature with an objective of cooking and the efficient use of the calorific value of the cooking fuel is given only a cursory attention by Chemical Engineers as it forms an insignificant component of the household monthly energy budget. In USA, the monthly car gasoline bill is probably much more than the heating and cooking energy (gas. electricity etc) bill which is only a small fraction of the total monthly energy bill. Thus, the focus of many Chemical engineers is, developing more fuel efficient and non polluting cars and better combusting fuels and not on thermally efficient cooking devices .

    In India however, with 16% of world’s population, which needs to be fed at least 2 square meals a day uses anywhere from 28 % to 40 % of the national energy consumption in achieving this cooking. This is a biggest chunk of the entire energy consumption pie for a nation and has not received the type of attention the other energy consuming sectors (Industry, about 40%, Transportation, about 25 %) have received. Since cooking and heating are typical Chemical engineering processes responsible for Physico- Chemical and biological changes, they can be tackled using the same principles of Chemical engineering.

    In this seminar, we discuss the design and operation of stoves used for cooking, its useful thermal efficiencies, how they can be mathematically modeled, scaled up and its operation in cooking of typical Indian food item such as Rice and lentils. The kinetics of cooking has also been modeled and an attempt is made to obtain the kinetic parameters.

    Aniruddha B. Pandit was born on 7th December 1957 in Mumbai, Maharashtra. He earned his B. Tech (Chem) degree from Indian Institute of Technology(IIT), Banaras Hindu University in 1980 and earned his Ph.D. (Tech) degree from University Department of Chemical Technology (now ICT), in 1984. From 1984 till 1990 he worked in the Department of Chemical Engineering, University of Cambridge, United Kingdom, working in the area of bubble break-up and design of multiphase reactors. He developed many novel designs of gas-liquid contactors and also developed new impeller designs.

    After returning to India in 1990, he joined ICT as a UGC Research Scientist ‘B’ and was subsequently promoted to Scientist ‘C’ (Professor’s Grade) in 1996. He was instrumental in starting a major activity & program in the area of Hydrodynamic Cavitation for intensification of physical and chemical processing applications. He has successfully exploited the cavitation phenomena for a variety of operations such as crystallization, emulsification, nano-particle synthesis and processes such as esterification, oxidation etc.

    A unique creative approach of using fundamental knowledge, coupled with simple, elegant experiments has resulted into novel cavitational reactors. Prof. Pandit has authored over 250 publications, 5 books and over 12 chapters and has 5 patents & is on the Editorial board of four International Scientific Journals. He has guided 30 PhD’s and 55 master’s students so far.

    In addition to his research contribution, Prof. Pandit has contributed to innovation in teaching, at graduate and undergraduate levels, demonstration experiments for elaborating the physical principles of many chemical engineering operations. He is actively involved in working with committees in the area of harnessing solar energy & with tribal population in extending the chemical engineering principles for drying of farm/ forest product & water disinfection for potable water.
