  • stagnation pressure — The pressure at the stagnation point. It is the same as the total head or pitot pressure (i.e., the sum of the local atmospheric pressure and the dynamic pressure) …   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 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

  • Pressure coefficient — The pressure coefficient is a dimensionless number which describes the relative pressures throughout a flow field in fluid dynamics. The pressure coefficient is used in aerodynamics and hydrodynamics. Every point in a fluid flow field has its own …   Wikipedia

  • Pressure measurement — The construction of a bourdon tube gauge, construction elements are made of brass Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges. A… …   Wikipedia

  • 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
