Dr Harish Viswanathan

Lecturer in Mechanical Engineering


Dr Harish Viswanathan is currently a Lecturer in Mechanical Engineering associated with Thermofluids Group.


Dr Viswanathan received his MSc degree in Industrial Mathematical Modelling and PhD degree in Mechanical Engineering from Loughborough University. He held a postdoctoral position at the Department of Chemical Engineering at the University of Colorado on a collaborative research work with Iowa State University, Princeton University and the National Energy Technology Lab in the USA. He started as an Applications Engineer with COMSOL Multiphysics worked for two years, and then worked for Mercedes-Benz Research and Development India as a Technical Leader in the area of Fuel Systems CFD for five years. Dr Viswanathan has authored several papers, has published in prestigious journals including the Journal of Fluid Mechanics and Physics of Fluids, and has filed 8 patents with Daimler.

Specialist areas of interest

Harish has special interests in modelling Fuel tank filling, aerodynamics and water management in cars, aero-vibro acoustics and effect of aerodynamics due to heavy wind and rain for passenger cars. Broadly he is interested in two-phase flows with turbulence, both reacting and non-reacting, phase change with evaporation, fluid-structure interaction, Aero-Vibro Acoustics and Conjugate Heat transfer
