| 摘 要： | 使用大涡模拟对凹腔内双驻涡冷态流场进行了分析研究.结果发现,在主流、前后壁面射流的情况下,凹腔在某些特定几何条件下会产生准周期生成和破碎的驻涡,同时研究了凹腔内准周期驻涡的生成发展的过程,得到了影响凹腔内涡演化的新结果.

| Abstract: | The large-eddy simulation(LES) has been used to described the computational simulation of the dual vortexes.The results indicate that in the case of primary airflow, fore-cavity and back-cavity flow injection,the vortexes could create in the cavity for some geometry conditions.The progress of trapped vortex development in the cavity is also investigated,the new result that influences the evolvement of vortexes in the cavity is obtained. |
