Thermo-osmosis
http://www.cailiaoniu.com/217128.html WebbThermo-osmotic slip—the flow induced by a thermal gradient along a surface—is a well-known phenomenon, but curiously there is a lack of robust molecular-simulation techniques to predict its magnitude. Here, we compare three different molecular-simulation techniques to compute the thermo-osmotic slip at a simple solid-fluid interface.

Webb18 feb. 2024 · Thermo-osmosis refers to fluid migration due to temperature gradient. The mechanistic understanding of thermo-osmosis in charged nano-porous media is still incomplete, while it is important for several environmental and energy applications, such as low-grade waste heat recovery, wastewater recovery, fuel cells, and nuclear waste … WebbThermal gradients lead to macroscopic fluid motion if a confining surface is present along the gradient. This fundamental nonequilibrium effect, known as thermo-osmosis, is held responsible for particle thermophoresis in colloidal suspensions.

Webb11 okt. 2024 · Shear flows play critical roles in biological systems and technological applications and are achieved experimentally using moving parts. However, when the system size is reduced to micro- and nanoscale, fabrication of moving parts becomes exceedingly challenging. We demonstrate that a heterogeneous nanochannel composed … WebbElectroosmotic flow (or electro-osmotic flow, often abbreviated EOF; synonymous with electroosmosis or electroendosmosis) is the motion of liquid induced by an applied potential across a porous material, capillary tube, membrane, microchannel, or any other fluid conduit. Because electroosmotic velocities are independent of conduit size, as long ...
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. Thermoosmose ist ein Spezialfall der Thermophorese (oder … Webb27 juni 2024 · 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 A modeling investigation on the thermal effect in osmosis with gap-filled vertically aligned carbon nanotube membranes
