Analysis of unsteady cavitating flow and pressure fluctuation around highly skewed propeller in non-uniform wake

摘要：

　　Numerical simulation of an unsteady cavitating flow around a highly skewed propeller in a non-uniform wake is performed based on an explicit LES approach with k-μ subgrid model.The predicted evolution of the unsteady cavitating flow and pressure fluctuation around a highly skewed propeller is in good agreement with experimental results.The relations between cavitation and pressure fluctuation are briefly analyzed based on the numerical results.Furthermore, numerical simulation of a propeller only have one blade in non-uniform wake is performed based on the same methods to analyze the relations between cavitation and pressure fluctuation clearly.
