WebApr 13, 2024 · Rayleigh–Bénard convection is a canonical flow in fluid mechanics, with applications in industry, geophysics, astrophysics and beyond. Investigations have examined linear and nonlinear stability as well as deriving analytical bounds on quantities of interest, while laboratory and numerical experiments have given insight into the behavior … WebThermal Convection. Convective heat transfer occurs whenever an object is either hotter or colder than a surrounding fluid. 2 Convection occurs only in a moving liquid or a gas, never in a solid. The basic equation for the rate of convection heat transfer is known as Newton's Law of Cooling: (12.2) where conv is the convective heat transfer ...
