choked flow

См. также в других словарях:

• 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

• 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

• 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

• Air flow bench — An air flow bench is a device used for testing the internal aerodynamic qualities of an engine component and is related to the more familiar wind tunnel. Used primarily for testing the intake and exhaust ports of cylinder heads of internal… …   Wikipedia

• Isothermal flow — is a model of a fluid flow, which remains in the same temperature. In this model the temperature is constant while the stagnation temperature is changing.The change in stagation temperature occur because the temperature is constant but the… …   Wikipedia

• Orifice plate — Flat plate, sharp edge orifice ISO 5167 Orifice Plate An orifice plate is a device used for measuring the volumetric flow rate. It …   Wikipedia

• Accidental release source terms — are the mathematical equations that quantify the flow rate at which accidental releases of air pollutants into the ambient environment can occur at industrial facilities such as petroleum refineries, petrochemical plants, natural gas processing… …   Wikipedia

• Tap (valve) — Spigot and faucet redirect here. For other uses, see Spigot (disambiguation). A valve tap is a noise made by the valves of internal combustion engines; see Poppet valve > Internal combustion engine. Indoor Tap commonly found in the bathroom or …   Wikipedia

• Venturi effect — The Venturi effect is the fluid pressure that results when an incompressible fluid flows through a constricted section of pipe. The Venturi effect may be derived from a combination of Bernoulli s principle and the equation of continuity. The… …   Wikipedia

• Steam whistle — A steam whistle is a device used to produce sound with the aid of live steam. Unlike a horn, the sounding mechanism of a whistle contains no moving parts (compare to train horn).The whistle consists of the following main parts, as seen on the… …   Wikipedia
