WebAt the corner, the flow has to turn though an angle $θ$ because of the requirement that the normal component of velocity at any solid surface has to be zero. To facilitate this turn we require an oblique shock at an angle $β$ to form at the corner. The shock angle can be calculated for a given Mach Number and angle $θ$.

WebJul 28, 2024 · The flow around the wing tips of a finite wing create an “induced” angle of attack on the wing near the tips. As the angle increases, the lift coefficient increases and this changes the amount of the induced drag. To separate the effects of angle of attack on drag, and drag due to lift, aerodynamicists often use two wing models.

Web1. There is a maximum turning angle θmax for any given upstream Mach number M1. If the wall angle exceeds this, or θ > θmax, no oblique shock is possible. Instead, a detached shock forms ahead of the concave corner. Such a detached shock is in fact the same as a bow shock discussed earlier. 2.
