Subsonic mixing layer tests with Supramar_Groove
Profile for mixing layers at very high speeds and
low sigma no leading edge cavitation for angle of
attack range or - 3.5 degrees

Subsonic mixing layer tests with Supramar_Groove
The high speed profile 12 with thick profile
head without groove exhibits strong
cavitation. Cavitation incitation starts behind
the thick profile head downstream of
minimum static pressure. Cavitation due to
surface imperfections starts even more upstream

Subsonic mixing layer tests with Supramar_Groove
The high-speed profile with a groove. Now we
observe instead of cavitation a mixing layer
going well beyond the trailing edge At the free
tip of the profile we observe partial separation
of the mixing layer due to the positive pressure
gradient towards the trailing edge, this is clear
indication that the mixing layer behaves as an
attached boundary layer
