Rayleigh entropy

WebThe Rayleigh flow model reaches maximum entropy at M = 1.0 For subsonic flow, the maximum value of H occurs at M = 0.845. This indicates that cooling, instead of heating, causes the Mach number to move from 0.845 to 1.0 This is not necessarily correct as the stagnation temperature always increases to move the flow from a subsonic Mach number … WebTherefore, the Rayleigh flow model is critical for an initial design of the duct geometry and combustion temperature for an engine. The Rayleigh flow model is also used extensively with the Fanno flow model. These two models intersect at points on the enthalpy-entropy and Mach number-entropy diagrams, which is meaningful for many applications.

WebJan 9, 2024 · The entropy fluctuations can be viewed as waves that lead to a scattering of light if the Bragg condition is fulfilled. However, entropy fluctuations do not produce a frequency Doppler shift for the scattered light. Therefore, the entropy fluctuation leads to elastic light scattering, which is commonly called Rayleigh-center scattering.
