Bio

Dr. Ratna Kishore V. received his Ph. D. in Mechanical engineering from Indian Institute of Technology, Delhi (IITD) in 2010. His dissertation was titled, Experimental and Computational Investigations on Open Laminar Flames of Multi-Component Gaseous Fuel Mixtures. The objective of this research is to study the laminar burning velocity using Heat Flux Method, effect of stretch diffusive-thermal instability of multi-component fuel mixtures burning in air (21% O2 & 79% N2 by volume). The work also involves flames simulations for 2D slot burners and 3D flat flame burner using FLUENT. Dr. Ratna Kishore has published 5 research articles in international journals and 5 at international conferences.

His current areas of research are: Premixed Combustion for Multi-components Mixtures (for ex. Propane + hydrogen), High Temperature Natural Convection Flows and Flow through industrial valves.
