Dr. Raphael Mandel
Assistant Research Scientist
Raphael Mandel joined the S2TS lab as an undergraduate research assistant in winter 2010. After graduating with a B.S. in Mechanical Engineering from the University of Maryland in spring 2010, Raphael elected to stay with the S2TS lab as a graduate research assistant in order to pursue his Ph.D. As a graduate student, Raphael has received numerous awards, including the Dean’s Fellowship, ASHRAE Graduate Grant-In-Aid Award, EMERC Hulka Energy Research Fellowship, and L-3 Graduate Fellowship. In addition, Raphael was accepted into the Future Faculty Program and served as a Future Faculty Fellow, where he mentored graduate students and co-taught a course with a faculty member. In his dissertation research, Raphael developed and modeled a novel cooling concept utilizing Film Evaporation with Enhanced fluid Delivery System (FEEDS), capable of achieving high heat fluxes (>1kW/cm2) and heat densities (>490W/cm3) at high vapor qualities (>85%) and moderate pressure drops. He is currently employed as an Assistant Research Scientist in S2TS, where he serves as technical lead on numerous projects, and has authored or co-authored more than 25 publications in international journals and conferences.
Dr. Ratnesh Tiwari
Assistant Research Professor
Dr. Ratnesh Tiwari received his Ph.D. in Mechanical Engineering from University of Maryland in 2015. He received his undergraduate degree from the Indian Institute of Technology (IIT) Kanpur, India in 2006. Prior to joining the University of Maryland, Dr. Tiwari has worked in the process and oil and gas industry for more than six years in the area of Heat Exchanger design and process development. He has extensive experience of designing experimental loops related to thermo fluidic systems, microchannel heat exchangers and micro reactor design and building energy modeling. He is currently involved in design and development of low cost microchannel heat exchangers for industrial system. He is also working on techno economic analysis and market analysis of the ongoing research projects.
