【摘要】：基于RANS方程,采用VOF方法捕捉自由液面,通过自定义函数UDF在Fluent平台上建立了三维数值波浪水池,模拟了规则波的生成、传播和消波,发现波陡对数值造波的精度有较大影响。求解了规则波中顶浪航行的方尾船模型的波浪力,并与试验结果和势流理论结果进行了比较。结果表明,基于RANS方程的波浪力计算结果与试验结果和势流理论结果吻合良好,在长波中与试验值更接近。
[Abstract]:Based on the RANS equation, VOF method is used to capture the free surface of liquid. A three-dimensional numerical wave pool is established on the Fluent platform by the self-defined function UDF. The generation, propagation and elimination of regular waves are simulated. It is found that the steepness of the wave has a great influence on the accuracy of numerical wave generation. In this paper, the wave forces of a rectangular stern ship model with the top wave in a regular wave are calculated and compared with the experimental results and the potential flow theory. The results show that the calculation results of wave force based on RANS equation are in good agreement with the experimental results and the potential flow theory, and are closer to the experimental values in the long wave.
