Stagnation pressure definition

Stagnation pressure means the pressure measured at a point in a flowing gas if it were to be brought to rest by means of an isentropic process.
Stagnation pressure means the pressure measured at a point in a flowing gas if it were brought to rest via an isentropic process.
Stagnation pressure means the pressure measured with respect to absolute zero pressure, which is exerted at a point at rest relative to the air around it;

  • 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).

  • 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).

  • 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 for all arcjet conditions was measured using water-cooled pitot probes.

  • Stagnation pressure was averaged over the cross section: , inlet stagnation pres- sure (x/h1 = 2.); ——, exit stagnation pressure(x/h1 = 3.).

  • 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.
