Measurement of 3D airblast swirl atomization field at low temperature with off-axis holography

  • 摘要: 为研究低油温工况下气动旋流雾化喷嘴近场雾化特性,建立了25 kHz皮秒脉冲激光离轴全息系统,对1 kPa气压、0.03 MPa油压和–40~28 ℃油温工况下喷嘴下游30 mm内近场雾化过程进行了三维可视化测试。实验获取了包含非球形液滴的近喷嘴雾化场清晰图像,记录了液膜袋状破碎与液丝分解等典型雾化动态过程。通过颗粒识别与定位,获取了雾化场中尺寸30~1500 μm的液滴粒径及三维位置,统计得到雾化场索特平均直径(SMD)的三维分布信息。研究发现:在气压1 kPa、油压0.03 MPa工况下,液滴粒径主要分布在200 μm以内,其中30~40 μm粒径占比最高,均在15%以上;三维粒径分布表现为雾锥中央粒径较大,边缘区域粒径较小;油温降低对雾化效果恶化显著,使雾锥体积缩小、雾化液滴密度降低且均匀性下降;油温从28 ℃降至–20 ℃时,下游截面中心粒径从300 μm左右增大至450 μm以上,局部大于650 μm;–40 ℃时,喷嘴下游出现大型液柱与多枝状液膜、液丝结构,燃油分解破碎距离进一步延长。实验结果证实了高速离轴全息技术在低油温工况下喷嘴近场雾化特性三维可视化诊断中的可行性,获取的雾化场三维参数可为喷嘴结构设计优化及雾化模型研究提供数据参考。
