An analytical model has been developed and an approximate solution for the free vortex swirling supersonic flow through nozzles. Earlier work by Mager, is potential flow based. In the present model swirl number has been redefined to confine the flow properties within the valid range. Flow ...
chemically reacting flow is also irreversible. However, there are a large number of gas dynamic problems with entropy increase negligibly slight, which for the purpose of analysis are assumed to be isentropic. Examples are flow through subsonic and supersonic nozzles, as in wind tunnels and rock...
A stream tube at the nozzle wall is indeed a useful description of the nozzle, but the stream tube could be anywhere. For example, the flow over a modern transport aircraft wing at high subsonic-flight Mach numbers usually has a region of slightly supersonic flow—hence the label “super-...
Fig. 3. Critical flow in an idealized nozzle. A general one-dimensional, incompressible, nearly homogeneous, isentropic, and one-component critical flow rate for a sub-cooled liquid as follows: (10)Gc2=-xdvgdP+(vg-vf)dxdPt-1 where Gc, x, vf, vg, P, t are critical mass flux (kg/m2...

Section 3. For orifice applications in natural gas using the ISO expansion factor (YISO), the real isentropic exponent (κr) should be applied in the expansion factor equation. For other differential pressureflowmeters(venturi, subsonic nozzle, V-cone), the real isentropic exponent (κr) is co...
Summary: We examine the stability of stationary non-transonic waves for viscous isentropic compressible flows through a nozzle with varying cross-section areas. The main result in this paper is, for small viscous strength, stationary supersonic waves with sufficiently low density are spectrally ...
A refrigeration system is provided that comprises a compressor, condenser, a thermal expansion valve, an isentropic expansion nozzle, and an evaporator. An isentropic expansion nozz
