RÉSUMÉ

Numerical analysis is carried out for the case of Soret and Dufour effects on radiation absorption fluid past a linearly accelerated vertical porous plate in the presence of exponentially varying temperature and concentration in a conducting field. The presence of a homogeneous chemical reaction is considered. A magnetic field of uniform strength is applied perpendicular to the plate. The set of nondimensional equations that govern the flow are solved numerically by using the finite difference method. The pertinent physical flow parameters on the flow quantities are studied through graphs, and the variations in skin friction, Nusselt number, and Sherwood number are presented in tables. It is noticed that the velocity boundary layer thickness increases under the influence of both Dufour and Soret numbers, but a mixed effect is noticed in the case of temperature and species diffusion.
