Mass transfer and free convection through a porous medium by the presence of a rotating fluid

An analytical examination of steady, free convective flow and mass transfer through a porous medium bounded by a vertical porous plate in the case of a rotating fluid with a constant angular velocity and a constant temperature at the plate is presented. The fluid is assumed incompressible and viscous, and governing equations are defined for continuity, momentum, energy, and diffusion. Boundary conditions are configured to include the constant heat flux, the species concentration at the plate, and the suction velocity. The primary and secondary velocities were determined for different values of the modified Grashof number, Eckman number, and a permeability parameter. Increases in the Eckman number were accompanied by decreases in the primary velocity, which increased with increases in the permeability parameter or the modified Grashof number. The same was verified for the secondary velocity.
