燃烧室内三维层流的数字模拟

NUMERICAL SIMULATION OF THREE-DIMENSIONAL FLOWS IN COMBUSTION CHAMBERS

本文以SIMPLE方法为基础,发展了一种模拟燃烧室内三维层流的数值计算方法和计算机程序.对存在冷却槽、主燃孔等不同流动条件下的流态进行了数字模拟.所得结果与已有的数值计算结果的一致性良好.

On the bases of SIMPLE method, a numerical method and a computer program are developed to simulate flows in combustion chambers.The flows in combustion chambers with film cooling slots and secondary air holes are numerically simulated under different conditions.The results are in good accordance with those from the existed methods.
