Large-Eddy Simulation of Propulsor Cavitation
Abstract
Approved for Public ReleaseWe propose to develop the largeeddy simulation (LES) approach to simulate cavitating propulsor flows onunstructured grids. The objective is to develop the capability for highfidelity simulation of cavitation effects from inception through cloud cavitation, for propulsor flows. The methodology is novel and involves application of existing single grid incompressible and cavitating MPCUGLES, and the extension of overset MPCUGLES to predict cavitating flow. The incompressible simulations will be combined with an inception prediction model that is under development, and contrasted to the fully compressible simulations. Hydrofoil and propulsor configurations will be studied with comparison to experiment. Due to the use of unstructured overset grids and LES,the proposed work will also impact several other problems of Navy interest.
