Subsonic Measurements
Comparison of PSP, Pressure Sensitive Paint, pressure fields obtained at M=0.5 and M=1.6 (background image); angle of attack is 15 deg.
Pressure variation at M=0.5 is ~ 10 times less than that at M=1.6; flow structure is significantly different. Dynamic presentation was adjusted to display pressure-field details using same color scale.
