WebThermophoresis. Thermophoresis (also thermomigration, thermodiffusion, the Soret effect, or the Ludwig–Soret effect) is a phenomenon observed in mixtures of mobile particles where the different particle types exhibit different responses to the force of a temperature gradient. This phenomenon tends to move light molecules to hot regions and ... WebThermal diffusivity is a parameter to be taken into account; however, a high value does not necessarily mean that heat is better dissipated, since it is the ratio between the thermal conductivity and the volumetric heat capacity at constant pressure. It provides information about the competition between heat conduction and storing, and both can ...
