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.

Webb22 jan. 2016 · Thermo-osmotic flows – flows generated in micro and nanofluidic systems by thermal gradients – could provide an alternative approach to harvest waste heat. However, such use would require massive… Expand Highly Influenced View 9 excerpts, cites results and background Save Alert Webb20 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-osmotic routes, for different … getting on with occasion of long standing

Webb26 juli 2024 · Thermo-osmotic energy conversion using waste heat is one of the approaches to harvesting sustainable energy and reducing associated environmental impacts simultaneously. In principle, ions transport through a charged nanopore membrane under the effect of a thermal gradient, inducing a different voltage between two sides of … 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. WebbThe thermo-osmosis of a gas through a polymer membrane, in which it dissolves, occurs if a temperature gradient is imposed across the membrane. The derivation is presented of equations for the gradual change of the pressure difference across the film towards an eventual steady state. They extend beyond those of Denbigh and Raumann, who … christopher freyre freyre real estate
