Abstract
The present paper deals with the thermo physical properties of a Casson fluid through an oscillating vertical wall embedded through porous medium
under the influence transverse magnetic field, radiation, constant heat source and first order chemical reaction. The radiative heat loss is modelled by
using Rosseland approximation. Similarity variables were used to convert the partial differential equations into ordinary differential equation. The
transformed ordinary differential equations are solved numerically using Runge - Kutta -Fehlberg method with shooting technique. In order to get
perfect perception of the flow pattern we obtain the graphs of axial velocity, temperature and concentrations profiles for various governing
parameters viz. Casson parameter, Wall dilation ratio, Reynolds number, Grashoff numbers, Magnetic field parameter, Porous parameter, Radiation
parameter, Prandtl number, Heat source parameter, Schmidt’s number, Soret number, Chemical reaction parameter. Influence of Skin friction
coefficient, Nusselt number, and Sherwood number on both walls are discussed and presented through tabular form.
