By measuring the full temperature dependence of this effect for polystyrene latex suspensions, we show that the thermophoretic mobility (or “thermal diffusion … Webb1 aug. 2024 · Particles transport driven by a temperature gradient in a solution is known as thermophoresis or Soret effect. The drift velocity of a particle is expressed as , where is a thermophoretic mobility. Therefore, the thermophoretic mobility is a parameter to characterise the nature of thermophoresis, and the systematic measurement of for …
WebbThermophoretic velocity measurements are performed on monodisperse particles with electrical mobility diameters ranging from 30 nm to 600 nm and for a temperature gradient equal to 50 750 K/m. The results obtained show an increase in thermophoretic velocity as a function of the mobility diameter, contrary to what is observed for spherical particles in … WebbS5. Estimation of thermophoretic force and natural convection In this section, we try to estimate the magnitude of thermophoretic force FT. Thermophoretic velocity vT in the x-direction is phenomenologically described as vT = -DT(dT/dx) [1], where DT is a thermophoretic mobility. In experiments, the magnitude of DT is usually reported to be ...
