Rayleigh regime
Did you know?
In fluid mechanics, the Rayleigh number (Ra, after Lord Rayleigh ) for a fluid is a dimensionless number associated with buoyancy-driven flow, also known as free (or natural) convection. It characterises the fluid's flow regime: a value in a certain lower range denotes laminar flow; a value in a higher range, turbulent flow. Below a certain critical value, there is no fluid motion and heat transfer is by conduction rather than convection. For most engineering purposes, the Rayleigh nu… Web2 days ago · The general direct and inverse problems of turbidity of spheroids which are monodisperse in size and shape and fall in the Rayleigh–Debye–Gans (RDG) and Rayleigh scattering regimes are solved ...
