摘要
针对滑行艇瞬态水动力特性的预报问题,采用基于全六面体非结构化网格动网格技术求解粘性雷诺平均方程的FINE/Marine商用软件,使用自由液面捕捉法,结合SST k-ω湍流模型,进行数值模拟,分析了1.18 m滑行艇在不同航速下的水动力特性,其中自由液面捕捉采用BRICS离散格式.通过与已有的船模试验结果比较,表明文中的模拟方法可以很好预报船舶水动力特性.
In this paper FINE/Marine software was used to predict the transient hydrodynamic characteristics of planing craft. The SST k-ω turbulence model has been used in the viscous flow code. Non hexahedral structured grid was used with the viscous flow code for meshing the computational domain. Free surface capturing method is utilized to analyze the hydrodynamic characteristics of 1. 18 m planing craft at different speeds,in which the free surface was captured by BRICS discrete scheme. Comparison with the ship model test results indicates that the simulation method can be used to predict the hydrodynamic characteristics of the ship.
