For a mean friction factor of in a duct with initially supersonic flow prove that the maximum duct length lor y- is diameters. 1 1 Flow in Constant Area Ducts with Heat Transfer A frictionless flow process in a constant area duct with heat transfer is referred to as Rayleigh flow. Flows in many thermal systems can be closely approximated to this process. For example under some conditions heat transfer processes in heat exchangers and combustion chambers can be considered by ignoring frictional effects here the changes in low parameters on account of wall friction are negligible compared to hose due to heat transfer. Therefore such processes can be represented by Rayleigh process without sacrificing much accuracy. Besides this the analysis of many complicated problems is considerably simplified by using the Rayleigh flow model. 9 1 THE RAYLEIGH LINE rhe IricttOnless flow process with heat transfer in a constant area duct esưihed by a curve known as Rayleigh line Figure this defines J 0CLIS slate points during the Rayleigh process and satisfies are U i tIOns stalc continuity and momentum.
