Generate a vector of random numbers from Rayleigh distributions … 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 … See more The Rayleigh number describes the behaviour of fluids (such as water or air) when the mass density of the fluid is non-uniform. The mass density differences are usually caused by temperature differences. … See more Solidifying alloys The Rayleigh number can also be used as a criterion to predict convectional instabilities, such as … See more • Rayleigh number calculator See more For free convection near a vertical wall, the Rayleigh number is defined as: where: • x is the characteristic length • Rax is the Rayleigh number for characteristic length x • g is acceleration due to gravity See more • Grashof number • Prandtl number • Reynolds number • Péclet number • Nusselt number See more
