| 摘 要： | 该文以商用软件FLUENT为平台,以KCS算例为对象,进行了计及自由面和螺旋桨非定常旋转效应的计算。考察了时间步长、自由面是否固化、湍流模式和网格数量、计算策略对计算结果的影响,确定了工程适用的计算方法,并应用于9000TEU集装箱船舶,与试验结果比较,吻合良好。

| Abstract: | On the basis of FLUENT software and taking KCS as an example,applied research on viscous flow around container ship hull was carried out.The calculation took into account the free surface effect and the unsteady effect from pro- peller rotation.The influences of time-steps,using fixed or non-fixed free-surface,grid number,and strategy of unsteady cal- culation are investigated aiming to get an optimized combination for practical use.What is obtained from KCS proves the meth- od being suitable for 9000TEU.Computational results for both KCS and 9000TEU agree with test results. |
