WebIn such a diffuser, the APG is strong enough to cause appreciable instantaneous flow reversals (instantaneous reverse flow up to 30% of the time), but the time-average flow is non-separated. ( Okwuobi and Azad 1973 ) provide velocity profiles in a diffusor (upstream diameter 101.6 mm, divergence angle 8°, diffusor length 720 mm).
