【摘要】：關(guān)于輻射應(yīng)力的計(jì)算存在不同的理論解,目前對(duì)這些理論的驗(yàn)證較為匱乏。本文基于CFD軟件FLUENT,建立二維數(shù)值波浪水槽模型,計(jì)算得到與理論解符合良好的波動(dòng)過程。利用數(shù)值結(jié)果,研究輻射應(yīng)力的垂向結(jié)構(gòu)。結(jié)果表明,輻射應(yīng)力值在波峰至波谷區(qū)域存在突變,其表層積分值與表層以下輻射應(yīng)力不連續(xù)�；诰�性波動(dòng)理論,針對(duì)不同的入射波參數(shù)設(shè)計(jì)實(shí)驗(yàn),檢驗(yàn)現(xiàn)有輻射應(yīng)力理論的適用性。結(jié)果發(fā)現(xiàn),不同情況下適用的輻射應(yīng)力理論不同。在實(shí)際應(yīng)用中,應(yīng)當(dāng)根據(jù)不同波動(dòng)類型和計(jì)算區(qū)域選取合適的輻射應(yīng)力理論。
[Abstract]:There are different theoretical solutions to the calculation of radiation stress. In this paper, based on CFD software fluent, a two-dimensional numerical wave flume model is established, and the calculated results are in good agreement with the theoretical solution. The vertical structure of radiation stress is studied by numerical results. The results show that there is a sudden change in the value of radiation stress in the region from peak to trough, and the surface integral value is not continuous with the radiation stress below the surface layer. Based on the linear wave theory, experiments are designed for different incident wave parameters to test the applicability of the existing radiation stress theory. The results show that the radiation stress theory is different under different conditions. In practical application, appropriate radiation stress theory should be selected according to different wave types and calculated regions.
