A Combined Experimental and Numerical Study of Heat Transfer Characteristics for Methane/Air Flame Impinging Normally on a Flat Surface Available to Purchase

An experimental and numerical study has been conducted to determine the heat transfer characteristics for laminar methane/air flame impinging on a flat surface. A commercial numerical code (FLUENT) was used to simulate the laminar premixed flame. Simulation results were compared with the experimental results and there was good agreement between the results. The purpose of simulation is to understand the impinging flame structure and the chemical physical combustion process. Further, simulation results are presented to define the reasons for a sharp peak in radial heat flux distribution when the inner reaction zone was intercepted by the plate. Here, it has been observed that the resultant effect of peak in radial velocity, axial velocity and velocity magnitude along with peak in the temperature and temperature gradient caused that sharp peak in heat flux value in the radial direction.
