Understanding how fuels mix, ignite, burn, and disperse to support cleaner and safer energy systems.
My research connects combustion, fluid mechanics, and thermal sciences. I combine controlled experiments, optical diagnostics, and computational modelling to study fuel injection, mixture formation, ignition, and flame development.
At IIT Guwahati, I am developing these research directions through the Hydrogen, Energy and Combustion Systems (HECS) Laboratory, with an emphasis on hydrogen safety, low-carbon fuels, and thermal hazards in energy systems.
Investigating hydrogen ignition and flame propagation, alongside the dispersion of hydrogen following a leak. The focus is on understanding how mixing and flow conditions influence combustion and the formation of flammable mixtures.

Related publications →Examining fuel injection, jet development, mixture formation, and early flame-kernel growth. Experiments and modelling help relate injection and chamber conditions to ignition behaviour, including comparisons of laser and conventional spark ignition.
