Rayleigh benard convection scaling
WebNote that large-scale flow in Rayleigh–Benard convection exists not only in the´ very turbulent state but also near the onset of convective motion where the Rayleigh number Ra is just above the critical value for convection. For example, Charlson & Sani (1971) and Buell & Catton (1983) have made a linear stability analysis of a WebThermal boundary layer near roughnesses in turbulent Rayleigh-Benard convection: flow structure and multistability Physics of Fluids 2014 We present global heat-transfer and local temperature measurements, in an asymmetric parallelepiped Rayleigh-B ́enard cell, in which controlled square-studs roughnesses have been added.

In fluid thermodynamics, Rayleigh–Bénard convection is a type of natural convection, occurring in a planar horizontal layer of fluid heated from below, in which the fluid develops a regular pattern of convection cells known as Bénard cells. Bénard–Rayleigh convection is one of the most commonly studied convection phenomena because of its analytical and experimental accessibility. The convection patterns are the most carefully examined example of self-organizing nonlinear …
