随着计算机运算能力的快速增长，数值水槽模型成为海洋装备和沿岸工程中越来越重要的研究工具，而波浪传递过程中的衰减情况是衡量数值波浪水槽质量的重要指标。本文通过STARCCM+软件，使用不可压缩流体N–S方程与VOF流体体积法基于传统纯粘流和势粘流相结合的方式建立数值波浪水槽，分析并对比2种数值波浪水槽的性能。结果表明，相比纯粘流数值波浪水槽，基于势粘流相结合的数值波浪水槽的波浪在传递过程中衰减更小，具有更高的稳定性。
With the rapid growth of computer computing power, the numerical tank model has become an increasingly important research tool in marine equipment and coastal engineering, and the accuracy of wave generation is an important indicator to measure the quality of numerical water tanks. This paper is through STARCCM+ software，using the incompressible fluid N-S equation and the VOF fluid volume method, the numerical wave tank is established based on traditional pure viscous flow and combination with the potential viscous flow and viscous flow, and the performance of two numerical wave tanks is analyzed and compared. The results show, compared with the pure viscous flow numerical wave tank, the wave based on the viscous flow combined with the viscous flow is less attenuated during the transfer process and has higher stability.
