摘要：

针对翼板结合部流噪声控制问题,设计7种不同高度和间距的涡流发生器方案,采用数值模拟和试验相结合的方法开展降噪效果研究。由于在水中直接开展涡流发生器降噪试验验证存在较大困难,先选取在空气中进行数值模拟和试验验证,以分析确定涡流发生器方案的可行性。以SUBOFF模型为研究对象,采用大涡模拟的数值方法,以空气中非定常流体计算流体力学计算结果作为声源项,开展声类比方程的求解,获取流噪声的结果。通过不同涡流发生器方案的比较,分析涡流发生器的高度、间距这两个主要参数对翼板结合部流噪声的主要源头—马蹄涡控制的效果,确定针对SUBOFF模型具有最佳降噪效果的涡流发生器方案,并在消声风洞中对模型进行试验验证。研究结果表明,所设计的涡流发生器方案降低翼板结合部流噪声具有可行性,为后续在水中开展进一步研究奠定了基础。

Abstract:

To solve the problem of flow noise control in wing-plate junction, seven kinds of vortex generators with different heights and spacings were designed, and the noise reduction effect was studied by combining numerical simulation and experiment. Since it is very difficult to directly carry out the vortex generator noise reduction test and verification in water, numerical simulation and experimental verification in the air were firstly selected to analyze and confirm the feasibility of the vortex generator scheme. Taking SUBOFF model as the research object, the numerical method of large eddy simulation was used to solve the acoustic analogy equation with the result of unsteady flow as the sound source term, and the flow noise result was obtained. Through the comparison of different vortex generator schemes, the control effect of two main parameters, the height and spacing of vortex generators, on the main source of the wing-plate junction flow noise, namely, horseshoe vortex, was analyzed. Then the vortex generator scheme with the best noise reduction effect for SUBOFF model was identified. This was verified by the anechoic wind tunnel model test. It is proved that the proposed vortex generator scheme is feasible to reduce the flow noise in wing-plate junction, which lays a foundation for further investigation in the water.

Key words: flow noise control, vortex generator, anechoic wind tunnel test, large eddy simulation
