"WebSince the flow cannot pass through the plate, the fluid must come to rest at the point where it meets the plate. In other words, it ``stagnates.'' The fluid along the dividing, or ``stagnation streamline'' slows down and eventually comes to rest without deflection at the stagnation point. Bernoulli's equation along the stagnation streamline gives " - On the k-e stagnation point anomaly
