Fanno flow solved numericals
Web42. Define the term “Fanno flow”. A steady one-dimensional flow in a constant area duct with friction in the absence of work and heat transfer is known as “fanno flow”. 43. Define Fanno line. The locus of the state which satisfy the continuity and energy equation for a frictional. flow is known as “fanno line”. 44. The Fanno flow model is considered an irreversible process due to viscous effects. The viscous friction causes the flow properties to change along the duct. The frictional effect is modeled as a shear stress at the wall acting on the fluid with uniform properties over any cross section of the duct. 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 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. These relations are shown below with the * symbol representing the throat location where choking can … See more • Rayleigh flow • Isentropic process • Isothermal flow • Gas dynamics • Compressible flow See more 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.
