Stall fluid dynamics Wikipedia
A stall fence is a flat plate in the direction of the chord to stop separated flow progressing out along the wing Vortex generators tiny strips of metal or plastic placed on top of the wing near the leading edge that protrude past the boundary layer into the free stream.
9. Forced Convection Correlations
9.1 Flow over Flat Plate With a fluid flowing parallel to a flat plate we have several cases arise: Flows with or without pressure gradient Laminar or turbulent boundary layer Negligible or significant viscous dissipation effect of frictional heating 9.1.1 Flow with Zero Pressure Gradient and Negligible Viscous Dissipation
Boundary Layer Fluid Flow: Notes Layer Thickness Equations
Consider a fluid moving with a velocity U approaching a flat plate at rest as shown in Fig.16.5. At a section distance x from the leading edge let be the thickness of the boundary layer. At this section the velocity varies from zero at the plate to U at a distance from the plate.
Orifice Plate an overview ScienceDirect Topics
The orifice plate is the most commonly used flow sensor but it creates a rather large nonrecoverable pressure due to the turbulence around the plate leading to high energy consumption. An orifice plate has an opening that is smaller than the pipe diameter. The typical orifice plate has a concentric sharpedged opening.
Basic Understanding of Airfoil Characteristics at Low

Glossary of Terms PTI Plastic Injection Molding
STRIPPERPLATE A plate that strips a molded piece from core pins or core the stripperplate is set into operation by the opening of the mold. SUBMARINE GATE A type of edge gate where the opening from the runner into the mold is lo ed below the parting line or mold surface as opposed to conventional edge gating where the opening is
Morris 39s theory predicts the critical angle of attack for leadingedge stall onset as the condition at which a global separation zone is predicted in the solution for the inner flow. Morris 39s theory demonstrates that a subsonic flow about a thin airfoil can be described in terms of an outer region around most of the airfoil chord and an inner
