摘要
为了准确预报滑行艇的阻力性能,应用计算流体力学(CFD)方法,使用STAR-CCM+软件,并结合重叠网格技术和Savitsky方法,对滑行艇的三维黏性流场进行数值模拟和计算的不确定度分析。研究结果表明,滑行艇阻力、升沉及纵倾角等计算结果与试验数据吻合良好,滑行艇的艇底喷溅现象及水-气分布模拟正常,表明论文建议的方法可快速和准确地预报滑行艇的阻力性能。
In order to predict resistance performance of a planing craft accurately, the three-dimensional viscous flow field around the planing craft was simulated by using computational fluid dynamics(CFD) method, and combining with Savitsky method and overlapping grid technology. The software STAR-CCM+ was used, and uncertainty analysis was carried out. The results showed that the calculated results of the resistance, sinkage and trim angle of the planing craft were in good agreement with the experimental data, and the simulation of the spray phenomenon and water-air distribution due to the planing craft was normal. This study provides an effective numerical calculation method for resistance prediction of planing crafts.
