Development of Advanced Cryogenic Cavitation Modeling Capability Aided by Experimental Validation

摘要

The development of a robust cavitation modeling capability in a CFD solver called Loci-STREAM is presented in this paper. The flow solver integrates proven numerical methods for generalized grids and state-of-the-art physical models in a rule-based programming framework called Loci which allows: (a) seamless integration of multidisciplinary physics in a unified manner, and (b) automatic handling of massively parallel computing. Data from experiments involving cryogenic fluids are used to validate and improve cavitation models in the flow solver. The objective is to develop a robust and accurate cavitation simulation capability in complex geometries such as liquid rocket engine turbopumps requiring large unstructured grids.
