WebMar 5, 2024 · The transition to supersonic flow occurs when the area changes, somewhat similarly to Fanno flow. Yet, choking can be explained by the fact that increase of energy must be accompanied by increase of entropy. But the entropy of supersonic flow is lower (Figure 11.40) and therefore it is not possible (the maximum entropy at \(M=1\).). WebRayleigh flow is the specific case of frictionless flow in a constant-area duct, with heat transfer. Rayleigh flow applies to constant-area heat exchangers and combustion … WebMay 10, 2024 · Rayleigh Flow. Like Fanno flow, where heat addition tends to drive flow towards sonic conditions, regardless of initial velocity. Knowing heat input can allow you to find change in total temperature between two points. From there you can backtrack and solve for all other properties at those two points like how you would do it for Fanno flow. tim smith amp capital

WebIn constant area flow with heat addition (Rayleigh flow), the total temperature increases due to the addition of heat. In summary, the total temperature can decrease in Fanno flow and ID flow through a normal shock, while it remains constant in isentropic flow and increases in constant area flow with heat addition (Rayleigh flow).
