摘要
本文建立了一个预估螺旋桨非定常性能的基于速度势的非定常面元法,该方法中采用了双曲面元,避免了面元之间的缝隙,并采用迭代方法实现非线性的等压库塔条件。文中以第22届国际水池会议(ITTC)推进技术委员会推荐的HSP桨与D4679桨和挪威船舶技术研究所(MARINTEK)提供的PF-W-B桨为算例进行了考核计算,与试验结果和其他研究工作者的计算结果比较表明,螺旋桨的非定常性能预报的结果是令人满意的。
A numerical method to predict the unsteady performance of the propeller is presented by using potential based panel method, in which hyperboloidal quadrilateral panels with constant source and doublet distribution are employed and equal pressure Kutta condition at trailing edge is applied.A corresponding computer program is developed for this purpose. Two propellers, HSP and D4679, proposed by Propulsion Committee of 22nd ITTC and a propeller PF-W-B supplied by MARINTEK are taken as examples for validation. Comparison with experimental data and calculated results obtained by other researchers shows good agreement.
