Numerical investigation of a new LH2 centrifugal pump concept used in space propulsion

Journal Title: INCAS BULLETIN - Year 2018, Vol 10, Issue 2

Abstract

The present study deals with efficiency increase of a centrifugal pump for liquid rocket propulsion by using an innovative concept. With this new pump design the axial length will be reduced by 60% and 20% mass weight towards a classic two stage centrifugal pump. To estimate the performances, the CFD methods were used. The CFD analysis will be performed on 3D domains with the CFD commercial code ANSYS CFX. The numerical solvers used are pressure based with the SIMPLE method for RANS. The domain discretization was done by using dedicated grid generators like TurboGrid and ICEM CFD. The results were compared with a classic configuration with two stages in series. Centrifugal pump characteristics, such as pressure inlet-outlet variation, velocity and streamline patterns are presented in the paper.
