Natural Convection in Porous Media Induced by the Centrifugal Body Force: The Solution for Small Aspect RatioSource: Journal of Energy Resources Technology:;1992:;volume( 114 ):;issue: 003::page 250Author:P. Vadasz

Abstract: The analytical solution to the natural convection problem in a rotating rectangular porous domain is presented for a small aspect ratio of the domain. The convection results from differential heating of the horizontal walls leading to temperature gradients orthogonal to the centrifugal body force. The solution to the nonlinear set of partial differential equations was obtained through an asymptotic expansion of the dependent variables in terms of a small parameter representing the aspect ratio of the domain. The convection regime is apparent in the results, although it has a weak effect on the mean heat flux.
