Laminar seperation bubble

Tīmeklis2016. gada 24. marts · Laminar separation without transition and consequently re-attachment precludes hysteresis. The lift coefficient of the lower leg of the loops for all the presented Re cases is seen to coincide (with Re = 60,000), implying that the airfoil is experiencing laminar separation without transition or bubble formation in this regime. TīmeklisIn this study, the effect of perpendicular acoustic excitation on laminar separation bubble over a NACA2415 aerofoil and stall characteristics of the aerofoil was investigated experimentally at ...

The flat-plate … Laminar Separation Bubble. The problem of the laminar separation bubble may be summarized as follows [44]: the bubble is formed when the boundary layer Reynolds number at separation is greater than a certain critical value (Tani's [34] and Owen and Klanfer's criterion [36]), and the pressure recovered in the reattachment process, is less than a certain critical value (Crabtree's criterion [30]). touch it bring it busta rhymes
