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 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 ...

Thermophoresis in an absorbing aerosol
Journal of Aerosol Science, 1987Abstract Several one-dimensional model problems have been solved for the temperature and concentration profiles of an aerosol allowed both to absorb external radiation and to move under the influence of thermophoresis. Since the aerosol absorbs radiation, the quantity of energy deposited is proportional to concentration.

Biotechnological applications of thermophoresis
2011For over 150 years it is known that particles in a temperature gradient conduct a directed movement. This is called the Soret effect or thermophoresis. Still the underlying physical principles of thermophoresis in aqueous solutions are not totally understood.

The thermophoresis of solids in gases
Journal of Applied Mathematics and Mechanics, 2005A brief review of existing ideas on the nature of the thermophoresis of solids in gases is given. A method for calculating the rate of thermophoresis of coarse solids is described. A procedure for analysing experimental data and for choosing a high-quality material on the basis of this is proposed.

Thermophoresis of aerosols: a review
Journal of Aerosol Science, 1991Abstract The modern theory of thermophoresis was developed in the linear approximation with respect to small Knudsen numbers, the zero approximation corresponding to the Epst.ein result. To compare experiment. with the theory it requires measuring the dependence of the thermophoresis velocity or the thermophoresis force versus Kn.

Experiments on photophoresis and thermophoresis
Journal of Colloid and Interface Science, 1975Abstract An experimental technique has been developed for the precise measurement of radiometric forces. The results suggest that the photophoretic force due to sunlight on aerosol particles of approximately 0.5μ diameter in the upper atmosphere may be comparable with or larger than the particle weight. The thermophoretic results are in conflict with
