基于FLUENT软件模拟平面运动机构试验

Numeral Simulation of Hydrodynamic Tests Using FLUENT

通过对流体力学软件FLUENT的使用与研究,根据潜水器循环水槽水动力试验的原理,提出了一套潜水器的数字水动力实验方法。该方法能够完全模拟利用小振幅垂直平面运动机构进行的全部水动力试验,并得到相应的水动力系数。通过对某长航程潜水器的计算并与循环水槽试验结果对比表明,该方法有很强的实用性,可以满足潜水器在完成初步设计阶段后对于操纵性能预报的需求。

Based on the basic theory of hydrodynamic tests of Automatic Underwater Vehicle （AUV） and the experience of using the fluid dynamical simulation software FLUENT, a numerical hydrodynamic test method was brought up. This method not only simulates all the hydrodynamic tests which can complete by vertical planar mechanic machine （VPMM）, but also obtains all the hydrodynamic coefficients. Computational results of a Long-Endurance A UV show that coefficients put by this method is of high precision. This method can satisfy the requirements of maneuverability design and prediction during AUV＇s scheme design period.
