In this study, a cavitation model for propeller analysis was selected using computational fluid dynamics (CFD), and the model was applied to the cavitating flow around the Potsdam Propeller Test Case (PPTC) propeller. The cavitating flow around the NACA 66 hydrofoil was analyzed to select a cavitation model suitable for propeller analysis among various cavitation models. The present and the experimental results were compared to select a cavitation model that would be applied to propeller cavitation analysis. Although the CFD results using the selected cavitation model showed limitations in estimating some of the foam cavitation and bubble cavitation identified in the experimental results, it was identified that foam cavitation and sheet cavitation around the tip were well simulated.

船用螺旋桨空化流分析的空化模型研究

在这项研究中，使用计算流体动力学 (CFD) 选择了用于螺旋桨分析的空化模型，并将该模型应用于波茨坦螺旋桨测试案例 (PPTC) 螺旋桨周围的空化流。分析了 NACA 66 水翼周围的空化流动，以在各种空化模型中选择适合螺旋桨分析的空化模型。将当前结果和实验结果进行比较，以选择将应用于螺旋桨空化分析的空化模型。尽管使用所选空化模型的 CFD 结果显示在估计实验结果中确定的一些泡沫空化和气泡空化方面存在局限性，但已确定，尖端周围的泡沫空化和片状空化得到了很好的模拟。
