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.
