Numerical Analysis on Internal Flow Field in Crack During Cool Gas Filling of Simulating Motors

摘要:

对模拟发动机裂纹在冷流填充过程中的压强变化情况进行数值模拟,计算裂纹在冷流填充过程中的压强变化,讨论不同升压速率、裂纹不同位置、不同的裂纹开口比对裂纹内部压强变化的影响。

Abstract:

To analyze the internal flow field in crack during cool gas filling of simulating motors, the pressure distribution inside the crack was obtained and the relation between preservations rate, position of crack, width of crack and the pressure in crack was also discussed.
