investigation of flame location effect on flame temperature in premixed counterflow combustion of particle-cloud

the premixed counterflow flames propagation in combustion of mixture which is a uniform mixture of fuel particles and air is analytically studied. this analysis framework is based on thermal-diffusion model with assumption that the lewis number is unit and the strain rate is constant. velocity profile is assumed as a function of one variable like x. the structure of the flame is presumed to consist of three zones: preheat-vaporization zone, reaction zone and convection zone. the zeldovich number, based on the gas-phase oxidation of the gaseous fuel is large, and heat loss is neglected. this analysis leads to variation of the flame temperature based on the flame location. temperature profiles for different strain rates are also available, which is congruent with experimental and numerical standpoints of particles combustion.
