Theory of the soret effect

Webb1 jan. 2002 · The temperature gradient in the fluid induces the redistribution of surfactant molecules or ions near the particle. The redistribution leads to a loss in the balance of the stress on the particle surface, and that results in the grain movement along the temperature gradient.
