aerodynamics - What is the difference between flow separation …
Jun 17, 2020 · Flow separation can happen without stall, and it will reduce the benefit gained from a higher angle of attack in proportion to the extent to which the flow is separated, but stall …
Why does airflow separate from the wing during stall?
Jul 21, 2019 · What causes the airflow separation from the airplane wing, that triggers a stall? To be more precise, what is the detailed explanation of the physics for why flow separation occurs …
How to determine if flow transitions or separates from a Cp plot?
Specifically, what features on the plot do I look out for that can tell me if flow transitions or separates (e.g. inflection points, plateaus, etc) I know that a strong adverse pressure gradient …
Why does flow separation cause an increase in pressure drag?
Aug 29, 2024 · Let's use a cylinder as an example: Imagine in this picture the flow was attached. According to the answer I linked, the pressure behind the object will be lower when the flow is …
airfoil - What is the effect of flow separation on lift, pressure ...
Aug 26, 2017 · Separation thickens the boundary layer, substantially altering the shape around which the outer flow streams. The altered airfoil shape causes a reduction in the effective …
aerodynamics - Why does flow separation cause a loss of lift ...
Aug 19, 2024 · To illustrate the effect of flow separation on lift, consider what the flow outside of the boundary layer "sees" when flowing around the wing. At low angle of attack flow is …
What causes the adverse pressure gradient that leads to flow …
2 When reading about flow separation I generally see a diagram like this: imp source: Wikimedia commons This shows that the boundary layer slows as it passes over the wing, eventually …
Where is the spanwise flow? How does the span wise flow point …
May 31, 2017 · Before flow separation that hardly happens, only in the boundary layer, as @Peter Kämpf explains. At low angles of attack, for understanding purposes, it is probably best to …
Why does supersonic flight detach airflow from a wing?
65 Flow separation happens when the pressure gradient of the airflow along the flow path becomes too steep. In subsonic flow, the oncoming air is first decelerated ahead of the wing, …
What is the effect of airflow speed on separation?
Oct 6, 2019 · The boundary layer separation is due to flow deceleration as it moves away from the leading edge and an adverse pressure gradient appears (potential flow theory). The lower …
