由于网格划分中多种因素的影响,导致船体阻力等水动力性能的计算难以获得较精确的结果。文章针对粘性流体力学算法(FLUENT软件),探讨了影响船舶水动力学计算的若干网格因素,对网格生成中部分因素的影响进行了考察。通过一系列的计算、分析,提出改进计算的方案,确定了适用于工程实际计算的参数,据此对船体阻力进行了计算,与试验结果比较表明有较好的符合程度。
Because of the effect of many factors in mesh generation, it is difficult to get accurate results in calculations of resistance and other hydrodynamic perJbrmance. In view of the CFD code (FLUENT software), in the paper it investigates the infiuential factors in mesh generation and discusses some mesh factors which influence ship hydrodynamic' calculation. Through calculation and analysis, a solution of improving calculation is presented The parameters applied to engineering actual computation are confirmed Based on it, the ship resistance is' calculated, which meets well with the test result.
