Abstract
Numerical simulation was applied to study the effects of changing geometric parameters, which were slot height G and axial length of outer collar L, on jet attachment of counter-flow thrust vectoring nozzle in zero attack angle and subsonic conditions. Combined internal flow characteristics of different suction outlet pressure with pressure distribution of upper wall of outer collar, the range of suction outlet pressure when main flow is attached to upper wall is obtained. Moreover, the attachment point moves towards the inlet of outer collar with the increase of suction outlet pressure when attachment appears. And 0.2bar was set as the work condition of suction outlet pressure for subsequent study. Critical values for G (between 0.017m and 0.02m) and L (between 0.19m and 0.2m) were confirmed. Attachment can be avoided and the clearance between main flow and upper wall grows larger when increasing G or decreasing L, separately.
