WebAnalyzed flow around a re-entry capsule, including constructing Fanno-Rayleigh relationships to solve equations of state of a gas through a detached shock wave. Solved for accurate atmospheric gas conditions, and then compared with results from common Gas Dynamics equations utilizing calorifically perfect gas and isentropic assumptions.
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. For given upstream conditions … See more • Purdue University Adiabatic and Isothermal Fanno flow calculators • University of Kentucky Fanno flow Webcalculator • Maurice W. Downey, Gino Fanno See more As was stated earlier, the area and mass flow rate in the duct are held constant for Fanno flow. Additionally, the stagnation temperature remains constant.
