Examples of Stagnation pressure in a sentence
Stagnation pressure ratio = Pl/Pawhere:Pl = stagnation pressure, mm Hg.Pa = ambient barometric pressure, mm Hg.
Stagnation pressure contours computed for missile spinning at 60 Hz. Again, the vortices are more persistent on the refined mesh than on the baseline mesh: (a) baseline mesh and (b) refined mesh (cycle 1).
Stagnation pressure contours computed for missile spinning at 30 Hz. Note that the vortices predicted on the baseline mesh are diffused much more rapidly in comparison to those computed on the refined mesh: (a) baseline mesh and (b) refined mesh (cycle 1).
Figure 3.1 Supersonic Flow over a Backward Facing Step [27] The geometry used in the present study is same as the one investigated experimentally by Hartfield [28], which is presented in Figure 3.2. Dimensions for the geometry and the number of computational grid points used are given in Table 3.1. Stagnation pressure and temperature are used as boundary conditions at the inlet; while, static pressure is specified at the exit boundary.
Stagnation pressure is retrieved from the static pressure value by a local Mach number estimate in the measuring section which is known by the use of the area Mach number relation (see e.g. Anderson21) with the assumption of a unit exit Mach number.
Stagnation pressure was averaged over the cross section: , inlet stagnation pres- sure (x/h1 = 2.); ——, exit stagnation pressure(x/h1 = 3.).
Stagnation pressure for all arcjet conditions was measured using water-cooled pitot probes.

The boundary conditions in this simulation are as follows:• Stagnation pressure at the compressor inlet is used.
The pressure of the initial shock (Hugoniot pressure) is given by equation (1); the pressure of the steady flow (stagnation pressure) is calculated according to Bernoulli and is given by equation (2): Hugoniot pressure: Pshock = ρ 0vshockvimpact (1) Stagnation pressure Pstagnation = 1 ρ0v2(2)2 impactAnalytically, those two pressures are important since the Hugoniot pressure gives the maximum possible value for the impact and the stagnation pressure gives the expected reading when the flow stabilizes.
