WebThe bleed flow will be studied under two cases: one involving frictional effects i.e. Fanno Flow and the other involving heat addition i.e. Rayleigh Flow. These two. cause for change … WebApr 9, 2024 · The flow then follows the Fanno line again, almost reaching a choked condition before exiting the duct. Figure 5 Fanno and Rayleigh Line Intersection Chart. The Fanno flow model is often used in the design and analysis of nozzles. When does the Fanno line reach its maximum entropy? How is the Mach number of a Fanno flow determined?

The Fanno flow model begins with a differential equation that relates the change in Mach number with respect to the length of the duct, dM/dx. Other terms in the differential equation are the heat capacity ratio, γ, the Fanning friction factor, f, and the hydraulic diameter, Dh: $${\displaystyle \ {\frac … See more Fanno flow is the adiabatic flow through a constant area duct where the effect of friction is considered. Compressibility effects often come into consideration, although the Fanno flow model certainly also applies to See more The Fanno flow model is often used in the design and analysis of nozzles. In a nozzle, the converging or diverging area is modeled with isentropic flow, while the constant area section afterwards is modeled with Fanno flow.
