In the present study, an analysis is carried out to study the variable viscosity and chemical
reaction effects on the flow, heat, and mass transfer characteristics in a viscous fluid over
a semi-infinite vertical porous plate. The governing boundary layer equations are written
into a dimensionless form by similarity transformations. The transformed coupled
nonlinear ordinary differential equations are solved numerically by using the shooting
method. The effects of different parameters on the dimensionless velocity, temperature,
and concentration profiles are shown graphically. In addition, tabulated results for the
local skin-friction coefficient, the local Nusselt number, and the local Sherwood number
are presented and discussed.
