Abstract

An unsteady two dimensional free convection flow of a viscous incompressible fluid past an impulsively started semi-infinite vertical cylinder adjacent to a non-Darcian porous media in the presence of chemical reaction of first order is investigated. The governing boundary layer equations are formulated with appropriate boundary conditions and are solved using an implicit finite-difference method of Crank-Nicholson type. The problem is shown to be controlled by seven thermophysical and hydrodynamic dimensionless parameters, namely thermal Grashof number (Gr), species Grashof number (Gm), Darcy number (Da i.e. permeability parameter), Forchheimer number (Fs i.e. second order inertial porous parameter), Prandtl number (Pr), Schmidt number (Sc) and chemical reaction parameter (K1).The effects of thermophysical parameter on the transient dimensionless velocity, temperature and concentration are illustrated graphically. Also, the effects of the various thermo-physical parameters on the Skin friction, Nusselt number and Sherwood number are presented and discussed. This model finds applications in polymer production, manufacturing of ceramics or glassware and food processing.
