Petro Tel Distinguished Lecture - 2015
Prof. Aniruddha Pandit
Heating and Cooking Devices: Modelling and Designs; Energy and Costs
Monday, March 23, 2015
4.00 PM - 5.00 PM


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 cursory
attention by chemical engineers as it forms an insignificant component of the
household monthly energy budget. In the USA, the monthly car gasoline bill is
probably much more than the heating and cooking energy bill for gas, electricity,
etc. which is only a small fraction of the total monthly energy bill. Thus, the
focus of many chemical engineers is on developing more fuel-efficient and
non-polluting cars and better combusting fuels, and not on thermally efficient
cooking devices.

India, however, with 16% of the world’s population, uses anywhere from 28% to 40%
of the national energy consumption to achieve cooking of 2 meals per day. This is
the biggest piece of the entire energy consumption pie for a nation, and yet it has
not received the type of attention that other energy consuming sectors (industry,
about 40%; transportation and irrigation, about 25%, lighting about 8% ) 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,
their useful thermal efficiencies, how they can be mathematically modeled and scaled
up, and their operation in the cooking of typical Indian food items such as rice and
lentils. The development of a matching batch-cooker to go with the stove and its
design procedure will also be discussed. The kinetics of cooking has also been
modeled and an attempt is made to obtain the kinetic parameters. Using these kinetic
parameters, a continuous cooker, which could be useful for the Govt. of India’s
ambitious Mid- day meal scheme, has been designed and fabricated.

The seminar tries to send a message: there is fundamental science in mundane and
trivial activities as well and if studied and implemented, can have a major impact
on the national energy bill.

About the Distinguished Speaker

Professor Aniruddha B. Pandit is currently a Research Scientist and a Professor at
the Institute of Chemical Technology (ICT), Mumbai. Born in 1957 in Mumbai,
Maharashtra, Prof. Pandit earned his B. Tech (Chem) degree from Institute of
Technology, Banaras Hindu University in 1980 and his Ph.D. from University
Department of Chemical Technology, University of Mumbai. During his Ph.D.
(1980-1984), he also worked as an Associate Lecturer in the same department. Prof.
Pandit worked for the period 1984-1990 in University of Cambridge, United Kingdom as
a Research Associate. He developed many novel designs of gas- liquid contactors and
proposed hydrodynamic cavitation as an alternative means for physico-chemical and
biological transformation. He was instrumental in starting a major activity &
program in the area of hydrodynamic cavitation. Prof. Pandit has been singularly
responsible to propose, promote and apply the phenomena of hydrodynamic cavitation
for intensification of physical and chemical processing applications. His work on
microbial cell disruption for water disinfection has been recognized by
International Maritime Organization (IMO) as a most probable technique for Ballast
Water Treatment among other seven developed by the scientists in Japan, Germany, USA
etc. 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.
Prof. Pandit has authored over 300 publications, 3 books and over 10 chapters and
has 13 patents with over 7500 citations and is in the editorial board of several
international scientific journals. He has successfully guided 34 PhD’s and 60
master’s students so far.
