摘要
提出了一种新型碟形潜水器外形设计.在三维贴体坐标系下,采用有限体积法求解不可压缩的雷诺平均(RANS)方程,使用标准k-ε湍流模型实现方程的封闭,数值模拟了艇体周围的粘性流场.通过对不同雷诺数下的粘性绕流和阻力性能的研究,并与水池实验结果相比较,证明了数值计算在潜水器阻力性能研究方面的应用价值.
A new hull form of dish-shaped underwater vehicle was described. A finite-volume method of solving incompressible Reynolds-averaged Navier- Stokes （RANS） equations was used for the numerical simulation of three-dimensional viscous flow around the vehicle in body-fitted coordinate system. The k - ε turbulence model was employed to close the RANS equations. The resistance performance of the vehicle and viscous flow around it at different Reynolds numbers was investigated and compared with the experimental data. The results show that the compational fluid dynamics（CFD） method is effective for the resistance performance prediction of underwater vehicle with satisfactory accuracy.
