Abstract

In order to investigate the influence of bubbly flow on propeller wake

the wake dynamics characteristics of propellers in bubbly flow are numerically studied based on the SST

DES turbulence model and volume fraction equation

and the sliding grid technique.The KP505 propeller flow numerical model is verified.A propeller wake evolution model is proposed based on the evolution mechanis

m of propeller wake in multiphase inflow.The results show that the proposed model can accurately simulate the evolution process of propeller wake and reveal the triggering mechanism of propeller wake instability.The radial ventilation position affects the strength and dissipation of the tip vortex and hub vortex of propeller.The ventilation at the axis causes the hub vortex to expand and connects the tip vortex to form a vortex ring in the far field.The ventilation position moves towards the wing tip

and the vortex system at the wing tip accelerates and rapidly dissipates.The results have certain reference value for the design and manufacturing of propellers.

DOI: 10.6052/0459-1879-19-222 http://doi.org/10.6052/0459-1879-19-222 为了改善高速流动工况下水翼吸力面上流场的空化特性, 提出了水翼表面主动射流对绕水翼周围流动加以控制的方法. 基于密度分域滤波的FBDCM混合湍流模型联合Zwart-Gerber-Belamri空化模型, 分析了来流空化数为0.83, 来流攻角为8$^\circ$, 射流位置距水翼前缘为$x=0.19c$时, 主动射流对于水翼吸力面上流动的空化特性和水动力特性影响. 对回射流的强度进行了量化分析, 以探究回射流与流场空化特性的关系. 数值分析结果表明, 在射流水翼吸力面上的时均空泡体积为原始水翼的1/15, 使得流场内空化流动由云空化状态转变为较为稳定的片空化状态, 显著地削弱了云空化的发展. 此外, 射流极大地改善了水翼的水动力性能, 使得水翼的升阻比较原始水翼提高了22.9${\%}$, 空泡的脱落频率减少了26.2${\%}$, 空泡脱落所引起的振幅减小了9.1${\%}$. 射流大幅降低了水翼吸力面上低压区面积, 水翼吸力面上流体的逆向压力减小, 回射流强度降低; 同时, 射流使水翼吸力面上的边界层减薄, 增强了流动的抗逆压梯度能力, 一定程度上阻挡了回射流向水翼前缘的流动, 这也从机理上分析了主动射流抑制空化的原因.
