Abstract and Keywords

Abstract: In this paper, the very large eddy simulation (VLES) method coupled with the discrete phase model (DPM) is used to simulate the atomization process of the liquid jet in the transverse gas flow. The prediction results of different turbulence models at multiple grid scales are compared. The results show that the VLES method can predict the basic morphology and parameters of the transverse jet accurately. Compared to other turbulence models that show significant fluctuation in the simulation results across different grid scales, the VLES model is less sensitive to grid size and captures more intricate surface structures of liquid column fragmentation in flow field simulation. It has a significant advantage over the Reynolds-averaged Navier-Stokes (RANS) simulation method and greatly reduces computational cost compared to large eddy simulation (LES) method. It is a promising numerical research method in engineering practice.

Keywords: transverse jet; numerical simulation; very large eddy simulation (VLES); atomization; turbulence model

摘要和关键词

摘要: 文章使用超大涡模拟（very large eddy simulation，VLES）方法耦合离散相模型对液体射流在横向气流中雾化过程进行模拟，并对比多套网格尺度下不同湍流模型的预测结果。结果表明，VLES方法能够较为准确地预测横向射流的基本形态及参数。相对其他湍流模型在不同网格尺度下模拟结果波动明显，VLES方法对网格尺寸敏感度较低，并在模拟流场流动细节方面能够捕捉到更多液柱破碎的表面结构，较雷诺平均（Reynolds-averaged Navier-Stokes，RANS）模拟方法有显著优势，且计算量比大涡模拟（large eddy simulation，LES）方法大大降低，在工程实际运用中是一种颇具潜力的数值研究方法。
