In this study, an investigation of magnetohydrodynamics flow of Oldroyd-B fluid by a rotating disk with the influence of thermophoresis on the deposition of particles is discussed. Additionally, the Soret–Dufour effects are taken into consideration.

Thermophoresis of Aerosol Particles
Nature, 1962THE velocity of thermophoresis v of small aerosol particles of radius R, much smaller than the free path λ of the surrounding gas molecules, has been calculated by us1 in two ways: (1) as a limiting case of thermodiffusion; (2) by finding the momentum imparted to the particles by impact of molecules the velocity distribution of which is not disturbed ...

Thermophoresis and Thermoelectricity in Surfactant Solutions
Langmuir, 2010In electrolyte solutions, the differential migration of the ionic species induced by the presence of a thermal gradient leads to the buildup of a steady-state electric field. Similarly to what happens for the Seebeck effect in solids, the sample behaves therefore as a thermocell. Here, we provide clear evidence for the presence of thermoelectric fields

Experiments were conducted on the motion of micron-size, spherical latex particles in stagnant liquids due to applied temperature gradients. The phenomenon, called thermophoresis, has previously been reported for gases but not for liquids. Dilute suspensions of particles in water or n-hexane were trapped between two horizontal, parallel disks.

Thermophoresis of colloids by mesoscale simulations
Journal of Physics: Condensed Matter, 2012The motion of a colloid induced by a temperature gradient is simulated by means of multiparticle collision dynamics, a mesoscale simulation technique. Two algorithms to quantify the thermophoretic behavior are employed and contrasted. The validity of the methods is verified as a function of the temperature gradient, system size, and algorithm ...

Thermophoresis for spherical particles
Journal of Aerosol Science, 2013Abstract Prediction of thermophoretic migration of particles suspended in a fluid is of practical importance for many industrial applications including gas cleaning applications. The design of particle-laden fluid systems requires an estimation of the thermophoretical deposition rate, which depends on the temperature gradient and also on the ...

Observation of Slip Flow in Thermophoresis
Physical Review Letters, 2008Two differing theories aim to describe fluidic thermophoresis, the movement of particles along a temperature gradient. While thermodynamic approaches rely on local equilibrium, hydrodynamic descriptions assume a quasi-slip-flow boundary condition at the particle's surface. Evidence for slip flow is presented for the case of thermal gradients exceeding (

Molecular thermodiffusion (thermophoresis) in liquid mixtures
Physical Review E, 2005Thermodiffusion (thermophoresis) in liquid mixtures is theoretically examined using a hydrodynamic approach. Thermodiffusion is related to the local temperature-induced pressure gradient in the liquid layer surrounding the selected molecule and to the secondary macroscopic pressure gradient established in the system.
