Correlating equations for heat transfer by natural convection from horizontal cylinders to a cylindrical enclosure are obtained using a conduction boundary-layer model. The correlation is valid for heat transfer by conduction, laminar flow and turbulent flow. The results approach the correlation for heat...
A numerical simulation of the steady-state, laminar, two-dimensional, natural convection heat transfer in an open-ended channel partially filled with an isotropic porous medium is presented. The Darcy-Brinkman-Forchheimer model along with Boussinesq approximation is used to describe the fluid flow in...
Natural convectionheat transferfrom aThree dimensional conservation equations for mass, momentum and energy have been solved numerically to predict the natural convection flow and temperature field around a short or long horizontal solid cylinder in air for a uniform wall heat flux in the laminar ...
The magnetic field had taken a lot of interest due to its applications and studied wildly by designs, engineers and researchers. Ghasemi et al. [70] examined numerically the impact of magnetic field on the natural convection heat transfer in a square enclosure. This latter was filled with Al2...

Thermal convection within porous mediums has many practical applications, such as petroleum processing, groundwater flows, filtering, food processing, and fibrous insulation15. There are two different models for the heat equation related to the two phases of the porous matrix. The first one is the...
