环驱式集成电机推进器定常水动力性能CFD分析
|
摘要
为了提高水下航行器性能,文中利用商用CFD软件ANSYSCFX对某环驱式集成电机推进器水动力性能进行分析,基于SSTk-ω湍流模型,建立了包括控制方程、计算域、网格生成、边界条件在内的集成电机推进器三维流场数学模型。给出环驱式集成电机推进器敞水特性规律,计算结果显示进速系数为0.9时,敞水效率可以到达58.32%。
To improve UUV performance, ANSYS CFX is adopted to complete the integrated numerical simulation of the flow field inside and outside the computational domain of the propulsor. Based on SST turbulence model, the numerical calculating model of the three-dimensional complex flow field of integrated motor propulsor is established to analyze its open water performance. The calculation results of the open water performance are obtained and analyzed. The calculation results show that: while the advance coefficient is 0.9, the open water efficiency can reach 58.32%.
