Abstract:
Under the steady-state working condition of a four-engine parallel test, the flow characteristics in the propellant supply pine with manifold assembly were simulated with CFD method. In addition, the transient flow characteristics of the manifold assembly was also analyzed during the engine startup. The calculated results show that the uniformity of velocity field and pressure field at each engine inlet in the four-engine parallel test with manifold can meet the requirements of transient flow in the pipes during engine startup. The test results show that the numerical calculation method can effectively guide the pipe design and improvement of the propellant supply system and predict the test results.
