In a flow field at the stagnation point
WebApr 7, 2024 · The stagnation region occupied by various surfaces with distinctive fluid models has gained much reputation and heedfulness in this regard. When a flow encounters a solid object, it results in stagnated flow because the local fluid velocity at the stagnation-point is zero due to maximum static pressure. Lin and Chen 1 1. WebNov 24, 2024 · A stagnation point is a point in a flow field where the local velocity of the fluid is zero. The Bernoulli equation shows that the static pressure is highest when the …
