"point" in inglés with examples - Collocation dictionary inglés
- In fluid dynamics, the flowfield near the origin corresponds to a stagnation point.
- In 2-D, streamlines are concentric closed curves that cross only at stagnation points.
- At a stagnation point, the velocity of the fluid is zero.
- This information can be used to show that the pressure coefficient at a stagnation point is unity (positive one):
- The streamline at a stagnation point is perpendicular to the surface of the body.
- This same value appears at the downstream stagnation point, this high pressure is again need to decelerate the flow to zero speed.
- The stagnation point on the topside of the airfoil then moves until it reaches the trailing edge.
- As the airfoil continues on its way, there is a stagnation point at the trailing edge.
- Once the initial transient effects have died out, the stagnation point is at the trailing edge as required by the Kutta condition.
- The dividing line between the upper and lower streamtubes intersects the body at the stagnation points.
