| 摘 要： | 本文提供了一个计算导管螺旋桨的定常及非定常性能的基于速度势的非定常面元法,桨和导管的相互影响是通过在时域范围内迭代计算处理.关于桨泄出涡与导管泄出涡之间的非定常干扰在时域内匹配,本文推荐采用考虑它们非定常影响的简化处理方法,以减少计算时间,提高计算效率.算例计算结果表明,本方法可以有效地应用于导管桨的定常及非定常性能的预估.

| Abstract: | A theoretical method for predicting the steady/unsteady performance of ducted propeller is presented,in which an unsteady panel method is applied both for the duct and propeller.The unsteady hydrodynamic interaction between the propeller and the duct is solved by an iterative method in the time domain.For the unsteady interaction of vortex shedding between the propeller and the duct in time domain,a simplified processing method is proposed and applied in this paper.The numerical results obtained by present method show that the proposed method is effective for predicting the steady/unsteady performance of ducted propeller. |
