Thermo-osmosis
WebbWe give a first review of experimental results for a phenomenon little explored in the literature, namely thermal osmosis or thermo-osmosis. Such systems are now getting increased attention because of their ability to use waste heat for separation purposes. We show that this volume transport of a solution or a pure liquid caused by a temperature … WebbAls Thermoosmose (englisch: thermal osmosis) wird in den Naturwissenschaften der Stofftransport durch Membranen unter Einwirkung eines Temperaturgefälles bezeichnet. Im Gegensatz zur Osmose unter isothermen Bedingungen tritt hier Materialtransport auch in Einstoffsystemen auf.

In principle, ions transport through a charged nanopore membrane under the effect of a thermal gradient, inducing a different voltage between two sides of …
WebbIt is shown that pore-water pressure evolution can be considerably affected by thermo-osmosis. Under the conditions of the problem considered, it was found that thermo-osmosis changed the pore-water pressure regime in the vicinity of the heater when the value of thermo-osmotic conductivity was larger than 10 −12 m 2 ·K −1 ·s −1.

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 … Webb24 nov. 2024 · Thermo-osmotic and related thermophoretic phenomena can be found in many situations from biology to colloid science, but the underlying molecular mechanisms remain largely unexplored. Using molecular dynamics simulations, we measure the thermo-osmosis coefficient by both mechanocaloric and thermo-os …

When a temperature difference is applied over a porous medium soaked with a fluid mixture, two effects may be observed, a component separation (the Ludwig–Soret effect, thermodiffusion) and a pressure difference due to thermo-osmosis. In this work, we have studied both effects using non-equilibrium thermodynamics and … filmfare achieversWebb26 jan. 2012 · thermo-osmosis The movement of liquid in a porous medium due to differences in temperature.
