Abstract
An exact solution of the problem regarding influence of chemical reaction and buoyant force on the heat and mass transfer in a radiative flow due to non-coaxial rotation of a disk and fluid at infinity is derived by using Laplace transform. Flow fields are displayed for various values of dimensionless parameters. Shear stresses at the surface of disk and shear stresses at the disk for very large time are calculated. The effects of Grashof number and Hartmann number on the steady state shear stresses at the disk are noted and presented.
