Abstract

Thermosolutal convection in an infinitely, extending layer of viscoelastic nanofluids in the presence of uniform vertical magnetic field with Soret and Dufour effect is investigated. The rheology of nanofluids is described by Maxwell's model. The coupled partial differential equations with the stress free boundaries are solved using the normal mode technique and linear theory. The first approximation of Galerkin procedure is used to obtain the numerical solution of the set of ordinary differential equation by using the software MATHEMATICA. The effects of the various parameters are shown graphically on both the stationary and oscillatory motions.
