Thermo-osmosis

WebbThe process of thermo-osmosis is the passage of a fluid through a membrane due to a temperature gradient. Under suitable conditions it gives rise to a stationary difference of pressure. The thermo-osmosis of a gas through a membrane in which it is slightly soluble is due partly to the temperature coefficient of its solubility and partly to the existence of … Webb30 sep. 2024 · In bulk fluids, thermo-osmosis is usually neglected due to the lack of a permeable medium. Whereas thermodiffusion or thermophoresis occurs in a mixture or suspension, thermo-osmosis occurs in both pure components and mixtures. In both cases, the temperature difference is the driving force.
