We investigate and model pressure effects on the turbulent burning velocity over a range of pressures turbulence intensities with direct numerical simulation (DNS) statistically planar premixed flames for lean hydrogen/air mixture. DNS results indicate that stretch factor has an impact flame surface area at elevated pressures. In particular, enhanced high increases ratio laminar velocities, dim...

A model for heat-recirculating micro combustor is developed. It investigates the structure of laminar, one-dimensional and steady state flame propagation in uniformly premixed wood particles with considering the effects of heat recirculation caused by configuration of micro combustor. The flame structure is divided into three regions: a preheat-devolatilization zone where the rate of the gas-ph...
