无人水下航行器壳体流体动力的计算

A study of autonomous underwater vehicle hull form using computational fluid dynamic

采用计算流体力学方法对无人水下航行器壳体流体动力特性进行数值模拟与计算。计算结果与风洞试验结果对比表明,该方法对无人水下航行器壳体流体动力特性的预测精度较高。该研究成果对无人水下航行器的外形设计具有缩短周期,节约费用和降低风险的效果。

In this paper such method is developed to simulate the flow past AUV hull. Contrasted the simulation results with the results of wind - tunnel experiment, the forecast precision about hydrodynamic dynamical performances of AUV hull objects shapes used this method is accurate comparatively. The result has important value for the design of underwater vehicles because which it can shorten the design time, save the expenses and decrease risk.
