Rayleigh temperature
The Rayleigh flow model begins with a differential equation that relates the change in Mach number with the change in stagnation temperature, T0. The differential equation is shown below. $${\displaystyle \ {\frac {dM^{2}}{M^{2}}}={\frac {1+\gamma M^{2}}{1-M^{2}}}\left(1+{\frac {\gamma … See more Rayleigh flow refers to frictionless, non-adiabatic flow through a constant area duct where the effect of heat addition or rejection is considered. Compressibility effects often come into consideration, although the … See more The area and mass flow rate are held constant for Rayleigh flow. Unlike Fanno flow, the Fanning friction factor, f, remains constant. These relations are shown below with the * symbol representing the throat location where choking can occur. Differential … See more • Fanno flow • Isentropic process • Isothermal flow • Gas dynamics • Compressible flow See more The Rayleigh flow model has many analytical uses, most notably involving aircraft engines. For instance, the combustion chambers inside turbojet engines usually have a constant area and the fuel mass addition is negligible.

This is because in glasses at higher temperatures the Rayleigh-type scattering regime is obscured by the anharmonic damping (typically with a ~λ dependence on wavelength), which becomes increasingly more important as …
WebRayleigh scattering, dispersion of electromagnetic radiation by particles that have a radius less than approximately 110 the wavelength of the radiation. The process has been named in honour of Lord Rayleigh, who in 1871 published a paper describing this phenomenon.
