Ferrofluids based on maghemite nanoparticles (NPs), typically 10 nm in diameter, are dispersed an ionic liquid (1-ethyl 3-methylimidazolium bistriflimide – EMIM-TFSI).

In this paper, a thermomechanical problem involving viscoelastic Timoshenko beam is analyzed from numerical point of view. The so-called thermodiffusion effects are also included in the model. written as linear system composed two second-order-in-time partial differential equations for transverse displacement and rotational movement, first-order-in-time temperature chemical potential. correspon...

Results on thermodiffusion of poly~ethylene oxide! and colloidal boehmite (g-AlOOH! rods in ethanol/water mixtures are presented. Data were obtained using thermal diffusion forced Rayleigh scattering. The sign of the Soret coefficient of the boehmite rods changes from positive to negative with increasing water content, i.e., at sufficiently high water content the colloidal particles move to hig...

Our main focus in this paper is to investigate the effects of Soret and Dufour known as thermodiffusion diffusion-thermo on moving plate copper water nanofluid. The set partial differential equations are converted into ordinary using appropriate similarity variables before being solved numerically bvp4c code Matlab software. results heat mass transfer, temperature concentration profiles well pr...

This paper investigates the influence of melting and thermo-diffusion effect on natural convection heat and mass transfer from vertical flat plate in a non-Newtonian fluid saturated non-Darcy porous medium. The wall and the ambient medium are maintained at constant but different levels of temperature and concentration such that the heat and mass transfer occurs from the wall to the medium. The ...

In a recent letter (C. Giraudet et al., EPL 111, 60013 (2015)) we reported preliminary data showing evidence of a slowing-down of non-equilibrium fluctuations of the concentration in thermodiffusion experiments on a binary mixture of miscible fluids. The reason for this slowing-down was attributed to the effect of confinement. Such tentative explanation is here experimentally corroborated by ne...
