The present study considers the numerical examination of an unsteady thermo-solutal mixed convection when the extra mass and heat diffusions, called as Soret and Dufour effects, were not neglected. The numerical simulations were performed in a lid-driven cavity, where the horizontal walls were kept in constant temperatures and concentrations. The vertical walls were well insulated. A finite vol...

-Dufour glands of minor workers of Camponotus aegyptiacus contain a mixture of linear and methyl branched hydrocarbons and a trace of dodecyl acetate. Major workers contain a similar mixture of hydrocarbons but also large quantities of dodecyl acetate, some other long chain acetates and traces of propionates and farnesyl acetate. Cataglyphis savignyi has pentadecane as the most abundant compoun...

Non-linear reaction-diffusion processes with cross-diffusion in two-dimensional, anisotropic media are analyzed by means of an implicit, iterative, time-linearized approximate factorization technique as functions of the anisotropy of the heat and species diffusivity tensors, the Soret and Dufour cross-diffusion effects, and five types of boundary conditions. It is shown that anisotropy and cros...

The focus of this treatise is on the scrutiny MHD heat and mass transfer motion upper convection Maxwell (UCM) fluid in a thermally radiated flat plate. models flow equations were considered when there temperature difference: Cattaneo-Christov model Soret-Dufour mechanisms. A magnetic field firmness was inflicted opposition to flow. inspection controlled by partial differential (PDEs). Suitable...

In this paper, we study the magnetohydrodynamics of Darcy flow in a non-Newtonian liquid. The influence thermophoresis on particle deposition is examined Maxwell nanofluid. our model, temperature distribution generated by Fourier law heat conduction with nonlinear thermal radiation and sink/source. We also examine Soret–Dufour effects mass concentration equations. Brownian thermophoretic diffus...

The aim here is to investigate the effects of convective heat and mass transfer in the flow of Eyring-Powell fluid past an inclined exponential stretching surface. Mathematical formulation and analysis have been performed in the presence of Soret, Dufour and thermal radiation effects. The governing partial differential equations corresponding to the momentum, energy and concentration are reduce...

The effect of thermophoresis on heat and mass transfer flow of a micropolar fluid in the presence of Soret and Dufour effects over a stretching sheet is investigated in the present analysis. The transformed conservation equations are solved numerically using an optimized, extensively validated, variational Finite element method. The influence of key non-dimensional parameters, namely, suction p...
