The theory of relative stream surface was applied to calculate and analyze the internal flow in a centrifugal pump of a liquid rocket engine.Streamline curvature method was used for calculation.Modularized calculation programs were developed to simulate the flow process in different parts of the pump
which allowed the calculation of every part to be conducted independently.The interaction between different parts was dealt with by the idea of mixing plane to convert the unsteady problem to steady problem.The effect of viscosity was corrected by several loss coefficients.The result shows that the inducer and the centrifugal impellers increase the pressure while the guide vane remains only changes the direction of the velocity
