Cavitationally Induced Physico-Chemical and Biological Transformations

Abstract:  Cavitation, which was and still is looked at, as an unavoidable nuisance in flow devices and systems, is however now a serious contender as an alternative means of local energy delivery for intensification of physico- chemical and Biological processing. 
Initial skepticism about cavitation as an alternative mode of energy supply is being replaced by optimism with a better control over its dynamics, showing applications involving specialty chemical synthesis to cold fusion and has been taken as an active area of research by many other groups from USA, UK, Spain, Germany, China, Japan and the Netherlands.
In this talk, we take a stock of the situation after three decades of work published in the area, with several hundred articles appearing in Journals & conference proceedings. The talk describes the fundamentals of different means of cavity generation and control of its dynamics as a physical phenomenon and its possible applications. The rich knowledge base created on single cavity and cavity cluster dynamics and the operational and controlling parameters to exploit these effects will be discussed. A link of Cavity Dynamics and its effects on physic-chemical and Biological system will be established. Applications in the area of cell disruption for intracellular enzyme recovery or potable water disinfection, chemical synthesis such as hydrolysis, oxidation and esterification, emulsification and nano-suspensions will be described.

Speaker Information

Aniruddha B. Pandit 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), in1984. From 1984 till 1990 he worked in the Department of Chemical Engineering, University of Cambridge, United Kingdom as a Research Assistant & then as a Research Associate with Prof. J. F. Davidson, 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 on industrial scale. He has been an active industrial consultant for many large size national and international companies.

A unique creative approach of using fundamental knowledge, coupled with simple, elegant experiments has resulted into novel cavitational reactors. Prof. Pandit has authored over 418 research publications, 5 books and over 12 chapters (with over 30000 citations)and has 15 patents & is on the Editorial board of five International Scientific Journals. He has guided 51 PhD’s and 92 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. He is a president of a NGO named Land Research Institute dealing with the Energy and Town planning sector.

Prof. Pandit is currently Vice Chancellor of Institute of Chemical Technology, Mumbai. Prior to this he has acted as a Dean in his capacity of Research Consultancy and research Mobilization and HR for over 9 years. He has been the coordinator of ICT-DAE center for Chemical Engineering Education and Research since its inception in 2008. He has successfully guided and completed many international science collaborations with Universities from France, Australia and The Netherlands. He is also on the project appraisal and evaluation committees of the DST and UGC, Govt of India. He is currently serving as a member of the Board of Governors of the IIT Bombay. He has been an active industrial consultant to many national and international industries.
