Stagnation point flows in analytical chemistry and life sciences

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.
