stagnation point

stagnation point
The 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.

This stagnation point, she explained, can often be related to the search for identity and self-confidence in their respective fields which usually pushes people to perform to their best of ability.
Secondly, the previous correlation used piston temperatures local to the jet stagnation point region even though the correlation was for an overall heat transfer coefficient.
[8] analyse a micropolar fluid with MHD flow near a stagnation point. Thermal radiation and chemical reaction effects for the same type of fluid has been considered by Das [9].The first cited effect is also treated numerically by Mahmoud [10], considering a stretching surface with variable thermal conductivity.
Like others before him, Keenan believes that Restoration Theatre studies have reached stagnation point, but does not diagnose that the problem may be their repeated immersion in the problems of late seventeenth-century stage and statecraft rather than ones of more living relevance.
This differential pressure induced 1.8% oxygen quenching at the stagnation point. Therefore, the temperature was overestimated by 0.6 K at the maximum due to the pressure-sensitivity.
Then, it seems Gorla [6] has obtained numerical results for the micropolar boundary layer flow at a stagnation point on moving wall using fourth-order Runge Kutta method.
Everybody has a stagnation point and may be Khawaja Asif had reached stagnation point early, after continued interference by these members when he was speaking on the important issue of power crisis in the country, he added.
Since their arrest and the calls from the board of the syndicate and large sectors of the press community to call for the minister's resignation, the situation reached a stagnation point as both sides stay defiant.
Bhattacharyya [12-13] studied the boundary layer flow and heat transfer over an exponentially shrinking sheet and also discussed stagnation point flow and heat transfer over an exponentially shrinking sheet.
At the center of this divided airflow is a narrow region known as the stagnation point. The location of the stagnation point uniquely represents the wing's AoA.
