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. These properties make the … See more • Purdue University Rayleigh flow calculator • University of Kentucky Rayleigh flow Webcalculator See more
