本文用有限差分方法,将改进后的盲巷中用内燃设备时的二阶变系数线性抛物型浓度扩散方程化为能用计算机计算的差分格式。通过对计算结果的分析,讨论了不同情况下几种参数变化对浓度分布的影响。
In this paper, we use the finite difference method to transform the second-order linearly parabolic concentration-diffusion equation with variable coefficient in internal combustion equipment into a differential format that can be calculated by computer. Through the analysis of the calculation results, the influence of several parameters on the concentration distribution under different conditions is discussed.
