摘　　要：通过对NACA滑行楔形体进行数值仿真计算,验证多面体网格在滑行艇数值仿真计算上的精度,并尝试使用多面体网格改善滑行艇数值仿真计算中遇到的伪扩散问题。计算结果表明,基于多面体网格的滑行艇数值仿真计算的精度很高,能够满足工程需要;能够改善滑行艇仿真计算中遇到的伪扩散问题。本文进一步扩展了多面体网格在船舶与海洋工程领域的应用范围,并为滑行艇的数值仿真计算提供有益参考。In order to test and verify the applicability of the polyhedral mesh for numerical simulations of planing hulls,polyhedral mesh was used to predict a NACA planing wedge’s drag and lift.Calculation results were compared with model tests results and numerical results from other mesh forms.Moreover,polyhedral mesh was used to try to solve false numerical diffusion problems which may be met in numerical simulations of planing hulls.Results prove that polyhedral mesh can offer precise and reliable results for planing hulls and of good for controlling false numerical diffusion problems.
