摘要
遥控无人潜水器(ROV)功能多样,结构复杂,其流体动力参数的精确计算是一个技术难点,文章基于[k-ω]模型的SST(剪切应力输运)湍流模型,建立了ROV流体动力计算模型和数值风洞计算方法,得到了ROV流体动力的变化规律。结果表明,带有附体后ROV水平面不对称,在附体处压力及速度变化剧烈,导致ROV流体动力参数及流场有了很大变化。
It is a technical difficulty to calculate the rapidity when ROV carries some complex shape appendages.This paper is based on SST(shear stress transport)turbulence model of[k-ω]model calculation model of Hydrodynamics and numerical wind tunnel technique.The ROV hydrodynamic calculation model and numerical wind tunnel calculation method are established.The change law of ROV fluid dynamics is abtained.The results show that the horizontal of ROV with appendages is asymmetric,the pressure and speed change rapidly at the appendages,resulting in the great change of ROV hydrodynamic parameters and the flow field.The numerical prediction method is feasible and effective with practical value.
