Compressible flow — is the area of fluid mechanics that deals with fluids in which the fluid density varies significantly in response to a change in pressure. Compressibility effects are typically considered significant if the Mach number (the ratio of the flow… … Wikipedia
Potential flow — streamlines around a NACA 0012 airfoil at 11° angle of attack, with upper and lower streamtubes identified. In fluid dynamics, potential flow describes the velocity field as the gradient of a scalar function: the velocity potential. As a result,… … Wikipedia
Shape factor (boundary layer flow) — A shape factor is used in boundary layer flow to determine the nature of the flow.:H= frac {delta^*}{ heta}where H is the shape factor, delta^* is the displacement thickness and θ is the momentum thickness. Displacement thickness is defined as… … Wikipedia
Secondary flow — In fluid dynamics, a secondary flow is a relatively minor flow superimposed on the primary flow, where the primary flow usually matches very closely the flow pattern predicted using simple analytical techniques and assuming the fluid is inviscid … Wikipedia
Aerodynamic potential flow code — Aerodynamic potential flow or panel codes are used to determine the velocity and subsequently the pressure distribution on an object. This may be a simple two dimensional object, such as a circle or wing and it may be a three dimensional vehicle … Wikipedia
D'Alembert's paradox — In fluid dynamics, d Alembert s paradox (or the hydrodynamic paradox) is a contradiction reached in 1752 by French mathematician Jean le Rond d Alembert.[1] D Alembert proved that – for incompressible and inviscid potential flow – the drag force… … Wikipedia
