Turbulent Combustion

I worked on turbulent combustion modeling using CFD at the High-Speed Reacting Flow Laboratory (HiREF) of UTM, Malaysia. I derived​1​ and validated​1–3​ the Rε/k−ε turbulence model, I worked on RANS modeling​4​ of swirl and vortex/turbulent​5​ dominated cold​6​ and chemically​7​ reacting flows​8,9​, modeling supersonic combustion​10​ for pulse detonation engines​11–13​, large eddy simulation (LES)​14​ of gas turbine combustors​15​ (swirl combustors) and vortex combustors​16​ for micro-gas turbines.
