In a flow field at the stagnation point

On a streamlined body fully immersed in a potential flow, there are two stagnation points—one near the leading edge and one near the trailing edge. On a body with a sharp point such as the trailing edge of a wing, the Kutta condition specifies that a stagnation point is located at that point. The streamline at a … See more In fluid dynamics, a stagnation point is a point in a flow field where the local velocity of the fluid is zero. A plentiful, albeit surprising, example of such points seem to appear in all but the most extreme cases of fluid … See more • Stagnation point flow See more WebThe applied magnetic field exerts viscous drag forces on the flow field, which slows down the fluid’s motion and raises the skin friction coefficient as well as heat transfer on the …
