stagnation point
stagnation point[stag′nā·shən ‚pȯint] (fluid mechanics) A point in a field of flow about a body where the fluid particles have zero velocity with respect to the body. stagnation pointThe point on the leading edge of an airfoil where the airflow separates, with some going over and some under the surface of the airfoil. It is the point where the full dynamic pressure plus whatever static pressure is effective at the time will be felt. If the wing is swept, then only the component of flow at right angles to the wing's leading edge is stopped, and the line of contact is called a dividing attachment line. |
