摘要:
航天领域火箭发动机上的球阀性能要求高、工作条件恶劣，对球阀流场分布特性、流量系数特性和力矩特性的研究一直是关注的焦点，要得到较为精确的计算结果又节省大量试验经费，对球阀流场进行仿真研究是有效途径。以液体火箭发动机用球阀为例，建立了三维稳态仿真数学模型并进行仿真计算，然后与试验结果进行比较，验证了计算模型的正确性。
Abstract:
In the aerospace industry, the ball valve in rocket engine has high performance requirement and works in an extraordinary adverse condition. The study on flow field distribution, flow coefficient and torque characteristics of the ball valve has been a focus of attention. It is effective way to make numerical simulation of the flow field in the ball valve in order to achieve an accurate calculation result and cut off testing expenditure. The ball valve in a liquid rocket engine is taken as an example to establish the three-dimensional mathematical models for steady state condition and perform the simulation computation. The computed results are compared with the test results to verify the correctness of the mathematical models.
