超声速气流中横向射流雾化实验和数值模拟

Experimental and numerical simulation of atomization of liquid jet in supersonic crossflow

  • 摘要: 为了对超声速气流中的横向射流雾化过程进行研究,在直连式实验台上进行了超声速气流中的横向射流雾化实验,并对实验工况进行了数值模拟.超声速来流的马赫数为2,实验喷雾的动压比范围为1.~11.7,实验工质为水.采用纹影法对射流雾化过程进行了拍摄,得到了有雾化的超声速流场结构和穿透深度拟合公式.同时采用欧拉-拉格朗日两相流计算方法对实验工况进行了数值模拟,雾化模型采用了一种新型K-H(Kelvin-Helmholtz)和R-T(Rayleigh-Taylor)混合模型,数值模拟与实验结果符合较好.
