Abstract:
1. A computerized method of modeling fluid flow over porous blocks, comprising the steps of: establishing a set of variables V, E calculating temperature, pressure and velocity variation in fluid flow within a cavity as ∇·(V(ρ establishing boundary conditions for the calculation of temperature, pressure and velocity variation, wherein the cavity comprises a square cavity having a longitudinally opposed inlet and outlet; calculating a Nusselt number for each said porous medium as wherein h represents an averaged heat transfer coefficient calculated as where A represents a cross-sectional area of a porous block respectively formed from each said porous medium, T avg represents a temperature difference between an average surface temperature of the respective porous medium and a cavity inlet temperature T i , L represents a length of the cavity, and q represents a heat transfer rate, wherein a longitudinal length of each said porous block is 0.27 L; calculating a Grashoff number as wherein g is a center of gravity, β is a volumetric thermal expansion coefficient, v is a velocity along a first Cartesian axis, and T s is a surface temperature; and displaying numerical results of the calculated temperature, pressure and velocity variations in the cavity, wherein the numerical results include the Nusselt number and the Grashoff number.
