摘要: Abstract A boundary-layer solution for natural convection in rectangular enclosures containing a porous medium is presented. The Brinkman-extended Darcy model, which allows the no-slip boundary condition to be satisfied, used formulation. method of based on modified Oseen technique. flow field found governed by parameter E = Ra 0 Da / . Except thin region next wall, as → similar that given pure analysis. Based results obtained Nusselt number, it determined analysis applicable when −4 accuracies present and from approach are examined.
