Ducts are conduits or passages used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. The needed airflows include, for example...

Compressible Duct Flow with friction. This article concerns a gas flow with friction due to the boundary walls under consideration. This problem is same...

Fanno flow is the adiabatic flow through a constant area duct where the effect of friction is considered. Compressibility effects often come into consideration...
