摘要
论文以KP505螺旋桨模型为对象,基于ITTC规程对螺旋桨敞水性征数值预报方法进行了不确定度分析;分别采用SST k-ω湍流模型和考虑流态过渡的γ转捩模型进行螺旋桨的敞水性征数值预报.结果表明:γ转捩模型在敞水性征预报精度上与模型试验更为接近;其中层流与湍流流态过渡以及部分位置流动分离的捕捉是不同湍流模型在流场捕捉方面的主要差异.
Taking KP505 propeller model as the object,the uncertainty of numerical prediction method of propeller open water characteristics was analyzed based on ITTC code.SST k-ω turbulence model and γ transition model considering flow transition were used to predict the open water characteristics of propeller respectively.The results show that the γ transition model is closer to the model test in the prediction accuracy of open water characteristics.Among them,the transition between laminar flow and turbulent flow pattern and the capture of flow separation in some positions are the main differences in flow field capture of different turbulence models.
