摘要
某S弯进气道由于转接段出现很大的扩张角,使得进气道流场产生较大的畸变度,为改善进气道流场品质,设计在其转接段处安装一组涡流发生器来抑制气流分离。为了定量考察进气道流场总压畸变度,采用FLUENT软件模拟仿真进气道流场特性,分析其出口总压畸变特性,并对比分析涡流发生器不同的结构参数对出口周向畸变指数的影响。
After the serpentine inlet, the turn of the inlet had a large outspreaded angle, which leaded serious total pressure distortion in the inlet flow field. In order to improve the character of the inlet flow field, a team of the vortex generator was set ncar the turn. In order to quantificationally get the total pressure distortion of the flow field, the ＂fluent＂ software was used to simulate the inlet flow field, and then to analyze the outlet total pressure distortion. On the base of this, change the size of the vortx generator to Contrastively analyze the outlet circle distortion.
