摘要
合理的滑行面设计,是滑行艇设计中的关键问题.利用CFD软件FLUENT对滑行艇简化模型的流场进行数值模拟,得到简化模型的压力分布细节,并由此对滑行艇的滑行面进行改型,通过改型调整航态和艇底的水动压力分布,达到降低船舶阻力的目的.改型前后的实验结果显示:改型后滑行阻力与原型相比减小7%.研究表明:利用通用软件进行船舶流体力学的研究,是一个较为有效的方法;另外,通过合理布置滑行面可有效减小滑行艇滑行阻力.
An important issue in planing craft design is the planing surface design.Research started with numerical simulation of flow around simplified planing boat model in virtue of the CFD software FLUENT.Distribution of dynamic pressure on the planning surface was obtained in detail.According to the details,planing surface was modified to adjust the ship attitude and the distributing of dynamic pressure in order to reduce the resistance.Experiments were carried and the results showed that the modified one achieved 7% reduction of resistance.It is indicated that CFD software is a capable tool in marine fluids study;and suitability of planing surface plays an important role in resistance reduction.
