| 摘 要： | 后台阶流动是计算流体力学领域十分重要的课题,但是后台阶流动与化学反应耦合的数值研究则比较少见.文中使用雷诺应力模型模拟后台阶流动的速度场,使用标量联合概率密度函数(PDF)方程模拟化学反应项,并将化学反应项的结果作为源项引入雷诺应力模型,模拟了后台阶流动中的甲烷与氧气的缓慢氧化反应.结果发现:雷诺应力模型能够很好地模拟...

| Abstract: | The flow over backward-facing step is an important problem in computational fluid dynamic,but the numerical studies of such flow coupled with chemistry reaction are few.Reynolds stress model(RSM) was used in the simulation of the velocity field of flow over a backward-facing step and the chemistry reaction was simulated by using the composition probability density function(PDF) method.The slow oxidation reaction of oxygen and methane over the backward-facing step was simulated,in which the chemistry reactio... |
