摘要
Abstract
Aimed at the large distortion of the flow field at the outlet of low diverter subsonic S-shaped inlet,a new control method for reducing outlet distortion by reverse vortices generated by"Λ"type step is studied.The mechanism of the suppression of flow field distortion by"Λ"type step is analyzed by numerical simulation,and the influence law of step structure parameters on the total pressure recovery and flow field distortion of the inlet outlet under different flow conditionsn is given.The research shows that the effect of suppressing distortion is closely related to the geometric size of the step,and the reasonably designed step has obvious improvement effect on the outlet distortion.关键词
