This study focused on free convective MHD Casson fluid flow past a permeable vertical plate with microorganisms and Soret-Dufour mechanisms. The physical model is governed by system of partial differential equations (PDEs). set PDEs were overhaul into nonlinear ordinary equation considering acceptable similarity variable. spectral relaxation method (SRM) was utilized to obtain solution the equa...

Temporal and spatio-temporal instabilities of binary liquid films flowing down an inclined uniformly heated plate with Soret effect are investigated by using the Chebyshev collocation method to solve the full system of linear stability equations. Seven dimensionless parameters, i.e. the Kapitza, Galileo, Prandtl, Lewis, Soret, Marangoni, and Biot numbers (Ka, G, Pr, L, χ , M , B), as well as th...

The present research paper deals with the study of heat and mass transfer characteristics steady viscous incompressible two-dimensional Maxwell fluid flow past a stretching sheet under influence magnetic field Soret effect. A well-known non-Newtonian model is used to differentiate it from Newtonian fluids. physical problem gives set highly nonlinear-coupled partial differential equations that a...

An analytical study was performed to study effects of thermo-diffusion and chemical reactions on a three-dimensional MHD mixed convective flow of dissipative fluid along an infinite vertical porous plate with transverse sinusoidal suction velocity. The parabolic partial differential equations governing the fluid flow, heat transfer, and mass transfer were solved using perturbation technique and...

A theoretical model is proposed to predict Darcy-scale mass transport in porous media coupled with nonequilibrium heat transfer and taking into account the thermal diffusion process. volume-averaging technique was used approximations leading a two-equation or two-temperature for macroscale energy balance equations. Because of Soret effect, concentration deviation respect averaged value function...

Convective heat transfer using different nanofluid types is investigated. The domain is differentially heated and nanofluids are treated as heterogeneous mixtures with weak solutal diffusivity and possible Soret separation. Owing to the pronounced Soret effect of these materials in combination with a considerable solutal expansion, the resulting solutal buoyancy forces could be significant and ...

The motion of non-Newtonian fluid with heat and mass transfer through porous medium past a shrinking plate is discussed. obeys Casson model, generation, viscous dissipation, thermal diffusion, chemical reaction are taken in our considered. modulated mathematically by system non-linear PDE which describe the continuity, momentum, heat, equations. These equations transformed into ODE using suitab...

We performed systematic temperature and concentration dependent measurements of the Soret coefficient in different associated binary mixtures of water, deuterated water, dimethyl sulfoxide (DMSO), methanol, ethanol, acetone, methanol, 1-propanol, 2-propanol, and propionaldehyde using the so-called thermal diffusion forced Rayleigh scattering method. For some of the associating binary mixtures s...
