摘要

采用纹影成像和大涡模拟方法，在射流-横流参考速度比为VRref=1.5的情形下研究了激励频率(f=20Hz~100Hz)对声激励射流与横流相干流动的影响，阐释了声激励射流中的合成效应及其显著改善横向射流穿透和混合特性的作用机制。在不同的激励频率下，声激励射流在横流中的相干流动呈现出差异明显的演变发展特征，当激励频率超过特定的临界阈值，声激励能够诱导外部流体周期性吸入射流腔室，显著提升射流的瞬时峰值喷射速度，形成强壮离散涡环主导的起始流动形态并带来射流腔内的附加混合。与无激励稳定射流相比，声激励可以有效增强射流的穿透深度、扩散范围和混合均匀性，尤其是在f=100Hz时，在喷口下游x/D=2处的穿透深度可提升约160%，x/D=10处提升约130%；基于所设定的评价区域(法向Dy∈(0, 14D)和展向Dz∈(-5D, 5D))，其在x/D=2处即可达到稳态射流经历x/D=16以上的混合水平。引入基于膜片振幅定义的修正斯特劳哈尔数，本文声激励射流结构呈现合成射流效应的临界修正斯特劳哈尔数约为Stm,cr=0.004。

Abstract

The present study performs schlieren-imaging tests and large-eddy simulations to illustrate the effects of forcing frequency on flow dynamics of acoustically-excited transverse jets in crossflow, at a fixed referenced jet-to-crossflow ratio of VRref=1.5 and a wide range of forcing frequencies (f=20Hz~100Hz). Of particular interest is the finding that a synthetic jet effect could be generated in acoustically-excited transverse jet, showing a significant enhancement mechanism on the jet penetration and mixing in crossflow. Distinct flow regimes are also identified for the acoustically-excited jets in crossflow, depending on forcing frequency. When the forcing frequency exceeds a specifically critical value, the outer surrounding fluid could be suctioned into the jet plenum by the acoustic excitation, resulting in an obvious increase of the peak instantaneous ejecting velocity, forming strong individual vortex rings in the starting flow regime, and bringing additional mixing process inside the jet plenum. With respect to the unforced steady jet, acoustic excitation effectively increases the jet penetration depth, spread domain and mixing uniformity. Particularly at a high forcing frequency, such as f=100Hz, the penetration depth could be increased up to 160% at x/D=2 and 130% at x/D=10 approximately. Evaluated in a specified zone sized by Dy∈(0, 14D) in normal direction and Dz∈(-5D, 5D) in spanwise direction, the mixing after 2D at f=100Hz could reach the SMD level of the steady jet experiencing up to 16D. By introducing a modified excitation Strouhal number based on the vibration amplitude of loudspeaker diaphragm, a criterion of Stm,cr=0.004 is suggested for manipulating the synthetic effect approximately in the cur-rent acoustically-excited jet configuration.

Key words： jet-in-crossflow; acoustic excitation; synthetic jet effect; active flow control; penetration and mixing characteristics
