WebThe resulting relation is shown below where L* is the required duct length to choke the flow assuming the upstream Mach number is supersonic. The left-hand side is often called the Fanno parameter. Equally important to the Fanno flow model is the dimensionless ratio of the change in entropy over the heat capacity at constant pressure, c p.

WebFor a gas flowing steadily from a tank to a pipe under Fanno flow conditions (adiabatic), the procedure follows that of Fanno flow in Gerhart et al. (1992) and Munson et al. (1998). An example in Perry (1984) uses figures which represent Fanno flow for choked flow. The following equations are solved simultaneously to compute mass flow rate ...

WebThe characteristic aspect of Fanno flow is its consideration of friction. The main assumptions associated with Fanno flow are: the flow is steady, one-dimensional, and adiabatic through a constant-area duct, and the fluid is an ideal gas with constant specific heats. Compared to Rayleigh flow, Fanno flow accounts for friction but neglects WebApplications. 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. For given upstream conditions at point 1 as shown in Figures 3 and 4, calculations can be made to determine ...
