stagnation point

A stagnation point is a location in a flowing fluid—like air or water—where the fluid's velocity drops to zero as it encounters an obstacle or surface. At this point, the fluid's kinetic energy is converted into pressure energy, resulting in the highest pressure in that area. Imagine water flowing toward a rock in a stream; right at the front of the rock, the water momentarily stops before moving around it. That spot is the stagnation point. It’s important in aerodynamics and fluid mechanics because it helps understand pressure distribution and flow behavior around objects.
