A constant fin angle of 12 deg to the incoming freestream was held. The results were compared to the same fin mounted above a flat plate, and showed similar lines of upstream influence, primary separation, and inviscid shock angles. However, the body of revolution caused these lines to curve rather than maintain a constant slope in the farfield region. This is at odds with the quasiconical flow observed by the fin on the flat plate. Also compared to the fin on a flat plate, the peak and plateau normalized surface pressures within the separation region are less on the surface of the cylinder compared to the surface of the flat plate. These features can be attributed to the transverse curvature of the body of revolution. 收起
