WebMar 5, 2024 · The stagnation point can be seen from Figure 10.14 by ascertaining the location where the velocity is zero. Due to the symmetry the location is on "solid'' body on the x –coordinate at some distance from the origin. This distance can be found by looking the combined velocities as (10.3.1.18) U 0 = Q 0 2 π r r = Q 0 2 π U 0 Pressure Distribution 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.
