Sanatan Das, Mrinal Jana, Rabindra Nath Jana . Free and Forced Convective Flow in a Horizontal Channel Embedded in a Porous Medium. International Journal of Computer Applications. 65, 3 ( March 2013), 36-41. DOI=10.5120/10908-5836
Abstract
An exact solution of the governing equations has been obtained for the free and forced convection flow between infinitely long horizontal parallel plates embedded in a porous medium. It is found that the fluid velocity decreases with an increase in porosity parameter. It is also found that the critical Grashof number for which there is no flow reversal near the upper plate decreases with an increase in porosity parameter. Further, the fluid temperature increases with an increase in either porosity of the porous medium or the Grashof number.
