In order to effectively predict the performance of liquid-hydrogen inducer under rated conditions, a finite-volume difference scheme, an explicit time-propulsion method and a multi-grid method are used to solve the three-dimensional incompressible liquid-hydrogen induction wheel designed by Tsinghua University’s Department of Thermal Energy Engineering Viscous flow field. The calculation shows that the liquid hydrogen pump is reasonable in design and can meet the engineering requirements.
