ABSTRACT 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.

 

BIO

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), 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. He developed many novel designs of gas-liquid contactors and also developed new impeller designs.

ACADEMIC & RESEARCH CONTRIBUTION: 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 400 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 52 PhD’s and 90 master’s students so far.

Administrative Contributions: Prof. Pandit is currently Vice Chancellor of Institute of Chemical Technology, MumbaiHe is on the editorial board on 5 international journals and was an associated editor of Ultrasonic Sonochemistry. He has successfully guided and completed international science collaborations with Universities from France, Australia and the The Netherlands.
