Numerical simulation of hemispherical hydrogen–air flame propagation with heat losses

Abstract

Abstract The article presents numerical simulation of the propagation of hydrogen–air flame in adiabatic conditions and with the heat absorbtion on the wall. The results of experiments in a cylindrical shell of 4.5 m3 are compared with the results of numerical simulation. The quantitative agreement between the experimental and numerical results is achieved. It is shown that the numerical model of the combustion with the heat losses under the conditions of the experiment may account the heat losses as an integral effect of the heat absorbtion.
