S弯进气道中流场畸变的监测研究
FLOW DISTORTION MONITORING IN AN S-SHAPED INTAKE
-
Abstract: A series of experiments were made in an S-shaped air intake at high incidence.The observations show that larger the incidence,the more distorted the flow field.And further,there is a certain relation between high incidence,swirling flow,total pressure field and position angle φ of the flow with the lowest total pressure coefficient C p.The position angle φ is given as a better detective parameter which can monitor the distorted velocity and pressure field.
