Subsonic and transonic wind tunnel — ubsonic tunnelLow speed wind tunnels are used for operations at very low mach number, with speeds in the test section up to 400 km/h ( 100 m/s, M = 0.3). They are of open return type ( losses. Open wind tunnelThe working principle is based on the … Wikipedia
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
Rayleigh flow — refers to diabatic flow through a constant area duct where the effect of heat addition or rejection is considered. Compressibility effects often come into consideration, although the Rayleigh flow model certainly also applies to incompressible… … Wikipedia
Fanno flow — refers to adiabatic flow through a constant area duct where the effect of friction is considered. Compressibility effects often come into consideration, although the Fanno flow model certainly also applies to incompressible flow. For this model,… … 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
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
Choked flow — is a compressible flow effect. The parameter that becomes choked or limited is the velocity or the mass flow rate. Choked flow is a fluid dynamic condition associated with the Venturi effect. When a flowing fluid at a given pressure and… … Wikipedia
Control flow diagram — Example of a so called performance seeking control flow diagram .[1] A control flow diagram (CFD) is a diagram to describe the control flow of a business process, process or program. Contr … Wikipedia
Aerodynamics — is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object. Aerodynamics is closely related to fluid dynamics and gas dynamics, with much theory shared between them. Aerodynamics is… … Wikipedia
