摘要:
结合实际工程项目，对液体火箭发动机两级轴流氢燃料涡轮进行了三维非定常数值模拟。以动静叶排干涉、非定常叶片力和力矩为目标，对涡轮内部非定常流场进行了深入的研究分析，计算了涡轮性能曲线并与试验结果进行了对比。结果表明：所采用的计算方法可以很好地模拟涡轮内部的非定常流动现象，涡轮一级动叶叶片力和力矩的波动幅值分别达15.78%和17.31%。就涡轮效率而言，非定常与定常结果存在一定的差别，在偏离设计点工况，非定常结果比定常结果更加符合实际情况。
Abstract:
In combination with actual engineering project, three-dimensional unsteady flow field of two-stage axial hydrogen fuel turbine in liquid rocket engine (LRE) was simulated numerically. Taking rotor-stator interaction, unsteady blade force and torque as research objects, an in-depth analysis of unsteady flow field within the turbine was performed. Moreover, the performance characteristics of the turbine were calculated and compared with experimental results. The result indicates that the calculation method used in this paper can properly simulate the unsteady flow phenomena inside of the turbine, fluctuation amplitudes of blade force and torque on blade surface of 1st rotor approach 15.78% and 17.31% respectively. As for the efficiency, there is a certain difference between unsteady and steady simulation results. At off-design state, unsteady result is more accurate than steady one.
