摘　　要：首次运用类似 SIMPL E方法的控制容积积分法的思想 ,对层流预混平面火焰控制方程的各项分类处理 ,对源项线性处理。并运用于对甲烷 -空气的一维层流火焰计算 ,表明这种新方法易收敛 ,计算效率高。A control volume integral method similar to the SIMPLE is adopted. The one dimensional stable planar governing equations are derived on the assumption that the effects of viscosity, volume force, heat radiation and heat diffusion due to the concentration gradient are neglected. The terms in the governing equations for the premixed planar laminar flame are assorted and the source term is linearized. This method has been used to calculate a methane-air premixed laminar flame and the numerical results proved that this new method is an accurate and high efficient one.
