WebThe Rayleigh's quotient gives an approximate value of the fundamental natural frequency that is higher than the exact value. To show this, let an arbitrary eigenfunction,, be given … This means the Rayleigh number is a type of Péclet number.For a volume of fluid of size in all three dimensions [clarification needed] and mass density difference , the force due to gravity is of the order , where is acceleration due to gravity. From the Stokes equation, when the volume of fluid is sinking, viscous drag … See more 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 … See more Solidifying alloys The Rayleigh number can also be used as a criterion to predict convectional instabilities, such as … See more • Grashof number • Prandtl number • Reynolds number • Péclet number 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.
