Presence of areas with abnormally high and null friction corresponds to the boundary layer with detachment and large-scale structures formed at the barrier flow.

x, y (mm) - longitudinal and transverse coordinates; U, U', V, V', (m/s) - longitudinal averaged velocity and its RMS pulsations, temperature (T, K), correlations U'V' (m 2/s 2);
