基于OpenFOAM的全回转推进器非定常性能预估

摘要

本文选择某一全回转吊舱推进器为研究对象,运用任意网格面元法(AMI)CFD数值计算方法,计算采用的开源数值计算软件OpenFoam对全回转推进器非定常敞水水动力性能进行了研究分析.控制方程离散采用有限体积法,湍流模型选取SSTκ-ω 模型,速度压力耦合采用PIMPLE算法求解.通过与试验结果比较,验证了基于OpenFoam的非定常数值计算方法在全回转推进器敞水性能预报的可靠性和有效性.%In this paper, aAzimuth thrusterwas choosed as the research object to analyze the unsteadyhydrodynamic performance.Using solover in the open-source software OpenFOAM,the governing equation was caculated by finite volume method and the turbulence model was caculated bySSTκ-ωand the PIMPLE algorithm was used to solve Velocity coupled pressure terms.By compared with the experiment results, the reliability and validity of the unsteady numerical calculation method based on OpenFOAM are verified.
