为了进一步提高涡轮入口温度,提出一种新型气膜冷却方法~含化学热沉的气膜冷却方法。对于新方法来讲,化学热沉的存在会影响气膜孔下游的流场,从而影响主流与固体壁面的换热。建立简化理想化学热沉模型,采用标准k-ε湍流模型对该方法进行数值模拟,结果表明,化学热沉的存在降低了气膜孔出口下游不远处壁面附近的温度,同时增大了壁面处混合气膜与壁面之间的对流换热系数. 相似文献

Molecular dynamics (MD) simulation is carried out for the bubble nucleation of liquid nitrogen in explosive boiling. The heat is transferred into the simulation system by rescaling the velocity of the molecules. The results indicate that the initial equilibrium temperature of liquid and molecular cluster size affect the energy conversion in the process of bubble nucleation. The potential energy of the system violently varies at the beginning of the bubble nucleation, and then varies around a fixed value. At the end of bubble nucleation, the potential energy of the system slowly increases. In the bubble nucleation of explosive boiling, the lower the initial equilibrium temperature, the larger the size of the molecular cluster, and the more the heat transferred into the system of the simulation cell, causing the increase potential energy in a larger range. 相似文献
