【论文摘要】 本研究对一单人赛艇进行黏性绕流场数值模拟,得到不同航速下的艇体表面压力、黏性阻力及黏性阻力系数等流场特征值与试验结果吻合得较好;还计算出形状因子(1+K),与经验公式计算结果相符合。在此基础上对带自由液面赛艇的黏性流场进行数值计算,得出艇型设计所关心的水动力性能参数,包括艇体表面压力分布、阻力及阻力系数、波形等流场信息,从而为赛艇设计提供依据。水利论文dM G]m/E9P

-dmc/BDm]b]7`0【英文论文摘要】 The computational fluid dynamics commercial software FLUENT was used to simulate the viscous flow around a single shell.The surface pressure,viscous resistance and viscous resistance coefficient at different velocity were obtained,which agreed well with the model tests. Also form factor got from the simulating agreed well with the result got from empirical formula. This paper also describes the simulation of viscous flow with a free surface around the shell.The calculated results shows that FLUENT effectively predict the resistance,resistance coefficient,wave profile and other hydrodynamics parameters,which are concerned in ship design.
