Ravi, M.R.

Areas of Interest: 
Heat Transfer, Computational Fluid Dynamics, Combustion, Biomass energy, Rural energy systems.

Details of current research areas:
  • Combustion characteristics of gaseous fuel mixtures, measurement of burning velocity of such mixtures, to investigate the effect of composition and equivalence ratio on burning velocity and stability regimes of flame. Computational simulation of open flames of such mixtures to study the effects of stretch field and preferential diffusion effects on the stability regimes.
  • Development and investigation of Biomass Gasification and Combustion systems, with specific interest in small scale (<=20 kW) systems for thermal and electrical applications, and powdery biomass based systems.
  • Energy Audit of rural industrial systems such as pottery kilns, soap stoves, smithy kilns etc. with an objective of fuel savings in such systems by applying basic principles of heat transfer and combustion. Development of energy-efficient alternatives for such systems.
