• 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
