| 摘 要： | 本文对汽油机燃烧过程的多维数值模拟进行了研究。采用有限差分法求解 Navier-stokes 方程。文中对方程组的离散方案进行了较为深入的分析,选用适当的有效粘度以考虑紊流的影响,可燃混合气的瞬时反应率遵守双分子碰撞的Arrhenious 关系,点火过程用局部加热过程考虑,最后给出了二维轴对称问题的解.通过对计算结果的分析表明,本模型对汽油机燃烧过程中缸内的流场,温度场、压力场和浓度场的分布及其随时间的变化情况都能定性地给予较为满意的描述.

| Abstract: | The multidimensional model for the Combustion Process of spark ignition engines is Presented in this paper.The Navier-stokes Equat- ion is solved by the binite difference method in which several discretizi- tag methods are used.To simplify expression of turbulence the concept of effective Viscosity is used for convenience.The instantane-ous relation of two molecules collision.The ignition process is considered as a local he- ating one around the spark plug.The Calculation result for the two-dimen- sional axisymmetrie proflem is given.and shows that the model can gualita- tively describe the flow Pattern and distribution of temperature.Pressure and concentration in the Cylinder. |
