 December 18, 2000, 23:24 Bouyancy convection #1 Zeng Guest   Posts: n/a Sponsored Links I want to check my code for the computation of buoyancy convection for incompressible fluid with Boussinesq approximation in laminar regime. would you please suggest me a reference? Thanks in advance.

If you agree, I am sure that following papers would be helpful to you. 1. "Laminar free convection in a vertical slot", J.W.Elder, J. Fluid Mech., vol. 23, pp.77-98, 1965 2. "Laminar and turbulent natural convection in an enclosed cavity", N.C.Markatos & K.A. Pericleous, Int. J. Heat & Mass Transfer, Vol. 27, pp.755-772, 1984 You can compare Nusselt number, streamfunction, local maximum velocity and so on. Sincerely, Jinwook

 December 19, 2000, 18:15 Re: Bouyancy convection #4 Chidu Guest   Posts: n/a There is another paper on natural convection in cavities: Chenoweth, DR, and Paolucci, S, Natural convection in an enclosed vertical air layer with large horizontal temperature differences, Journal of Fluid Mechanics, Vol. 169, pp. 173-210, 1986. As you can see it deals with large temperature differences, but there is also some comparisons to the Boussinesq equations. It is a numerical study. regards, chidu...
