Rayleigh flow equations
Did you know?
The Rayleigh flow model begins with a differential equation that relates the change in Mach number with the change in stagnation temperature, T0. The differential equation is shown below. $${\displaystyle \ {\frac {dM^{2}}{M^{2}}}={\frac {1+\gamma M^{2}}{1-M^{2}}}\left(1+{\frac {\gamma … See more Rayleigh flow refers to frictionless, non-adiabatic flow through a constant area duct where the effect of heat addition or rejection is considered. Compressibility effects often come into consideration, although the … See more The area and mass flow rate are held constant for Rayleigh flow. Unlike Fanno flow, the Fanning friction factor, f, remains constant. These relations are shown below with the * symbol representing the throat location where choking can occur.

The value of n is usually n = 1/4 for laminar flow and n = 1/3 for turbulent flow. The Rayleigh number is defined as: where: g is the acceleration due to Earth’s gravity
WebHeat transfer is the third main factor that can affect a compressible flow, after area change and friction. Rayleigh flow is the specific case of frictionless flow in a constant-area duct, … WebThe model of a two-dimensional fluid flow past a cylinder is a relatively simple problem with a strong impact in many applied fields, such as aerodynamics or chemical sciences, although most of the involved physical mechanisms are not yet well known. This paper analyzes the fluid flow past a cylinder in a laminar regime with Reynolds number, Re , …
