喷管分离流动与侧向载荷定常数值模拟
Stationary Numerical Simulation of Flow Separation and Side Load in Nozzle
利用商业CFD软件，进行了三维、有粘、定常计算，模拟了某液体火箭高空喷管地面条件下的分离流动。计算了多个不同入口总压下的工况。其结果预示了该喷管的分离流动在不同入口总压下的激波模态变化，并获得了非对称分离及其造成的侧向载荷的分布情况。计算为进一步相关研究打下了基础。
three-dimension, viscous and steady numerical simulation about serpentine flow was conducted in a high-altitude nozzle of a liquid rocket engine at the ground. The results with different inlet pressure were gotten by utilizing the FLUENT software. The transformation of shock pattern and the distribution of unsymmetrical separation and side load in the nozzle were primarily predicted by those results. The simulation provides key basis for farther study.
