| 摘 要： | 研究了基于CFD方法的钻井船月池流场及阻力性能。针对某阶梯型月池的钻井船,采用定常方法分析其阻力性能,并与模型试验结果进行比较,分析钻井船月池阻力数值计算方法的可靠性;采用非定常方法模拟月池内流体的非定常流动,分析月池附加阻力产生的原因。计算方法及所得出的结论可为具有月池的船舶阻力性能研究提供参考。

On lfow ifeld and additional resistance of moonpool in drillship with CFD |
| |
| Abstract: | This paper studies the lfow ifeld and resistance performance of the moonpool in a drillship with CFD. The resistance performance of a drillship with a step-style moonpool is analyzed with steady method, and is compared with the experimental results for validation of the calculation method. The lfow ifeld in the moonpool is simulated with unsteady solver for the analysis of the reason that causes additional resistance. The calculation method and the conclusions could provide references for the resistance research of the vessels with moonpools. |
