| 摘 要： | 采用直接求解RANS方程的方法对20艘散货船的绕流场和阻力进行了数值模拟,比较了标准模型、RNG模型及SST模型对数值计算结果的影响.通过与试验结果的详细对比,发现只要选取合适的湍流模型,数值模拟结果能够达到较高的精度,在1% -2%之间.这表明该数值计算方法能够满足工程的实际使用要求,可以在工程中推广应用.

| Abstract: | Drag and flow field around bulk carrier are investigated with numerical method.Reynolds average Navier-Stokes equation in conjunction with standard turbulence model,RNG turbulence model and SST turbulence model are solved respectively.Computation results agree well with experimental data,the precision is about 1%.It is shown that this numerical method satisfies the precision request of the prediction of the powering performance. |
