| 摘 要： | 气体混合是微流动系统的重要应用之一.本文使用DSMC方法,数值模拟了不同进出口压力下简单和复杂微通道内H2和O2的混合过程,并从满足完全燃烧的氢氧摩尔流量比的角度,讨论了进出口压力以及两种气体入口压力比和宽度比(截面面积比)对摩尔流量比的影响.

| Abstract: | Gas mixing is one of the most important applications in micro flow systems.The mixing processes of hydrogen and oxygen in simple and complicated microchannels were numerically simulated by DSMC under different inlet and outlet pressures in this paper,and the effect of pressure ratio and channel width ratio (cross section area ratio) of hydrogen and oxygen at inlet on the mole flow rate ratio of hydrogen and oxygen was discussed from the point of view of satisfying the need of perfect combustion. |
