  • Flow separation — All solid objects travelling through a fluid (or alternatively a stationary object exposed to a moving fluid) acquire a boundary layer of fluid around them where viscous forces occur in the layer of fluid close to the solid surface. Boundary… …   Wikipedia

  • stall — An aerodynamic condition in which the flow along the upper surface of the airfoil separates, resulting in a sharp reduction in the quantum of generated lift. An aircraft stalls after it has reached the critical angle of attack. The stalling angle …   Aviation dictionary

  • stall — An engine which stops unintentionally. The usual causes of stalling are: sudden increase in load without an accompanying increase in fuel flow (often occurring when a driver engages the clutch to drive away without increasing the engine speed)… …   Dictionary of automotive terms

  • Compressor stall — A compressor stall is a situation of abnormal airflow resulting from a stall of the aerofoils within the compressor of a jet engine. Stall is found in dynamic compressors, particularly axial compressors, as used in jet engines and turbochargers… …   Wikipedia

  • Dynamic stall — is a non linear unsteady aerodynamic effect that occurs when aerofoils rapidly change the angle of attack. The rapid change can cause a strong vortex to be shed from the leading edge of the aerofoil, and travel backwards above the wing. The… …   Wikipedia
