|Comparison of PSP
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
(Bi-Luminophore Paint, exposure time 10 ms, LED light source)
