Stagnation point — The stagnation point is a point on the surface of a body submerged in a fluid flow where the fluid velocity is zero. The Bernoulli equation shows that the static pressure is highest when the velocity is zero. The velocity is zero at stagnation… … Wikipedia
stagnation point — noun 1. : a point on the surface of a solid body immersed in a fluid stream which directly faces the stream and at which the stream lines separate 2. : a point near the leading edge or nose of a body placed in an airstream at which the airflow… … Useful english dictionary
stagnation point — The point on the leading edge of an airfoil where the airflow separates, with some going over and some under the surface of the airfoil. It is the point where the full dynamic pressure plus whatever static pressure is effective at the time will… … Aviation dictionary
Stagnation temperature — is the temperature at a stagnation point in a fluid flow. At a stagnation point the speed of the fluid is zero and all of the kinetic energy has been converted to internal energy and is added to the local static enthalpy. In incompressible fluid… … Wikipedia
Stagnation enthalpy — or total enthalpy ( h t ) is the enthalpy of a flow at a stagnation point. It is the enthalpy a flow would possess if brought to rest (zero speed) isentropically from speed v. h t = C p T + frac{v^2}{2}where, C p = specific heat capacity at… … Wikipedia
Stagnation pressure — In fluid dynamics, stagnation pressure is the pressure at a stagnation point in a fluid flow, where the kinetic energy is converted into pressure energy. It is the sum of the dynamic pressure and static pressure at the stagnation point. [… … Wikipedia
Flow measurement — is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive displacement flow meters acumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other 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
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
