Study on the characteristics of interaction flowfields induced by supersonic jet on a revolution body

Blog Article

The paper focuses on the triple jets interaction with a hypersonic external flow on a revolution body.The experimental model is a ogive-cylinder body with three supersonic nozzles, which are aligned along the flow direction.The freestream Mach numbers are 5 and 6.The spatial and surface flow characteristics are illustrated click here by the schlieren photographs and the typical pressure distribution.The results show that there are multi-wave system, separation, reattachment, multi-peak pressure, high-pressure and low-pressure zone boundaries obvious distinction in tri-jets interference flowfield.

The present paper also analyzes read more how do the pressure ratio, the angle of attack, and Mach number effect on tri-jets interaction characteristics.
