Thermo-osmosis

Webb21 dec. 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 thermo-osmotic flows, which are up to now only predicted for special and expensive materials. There is thus an urgent need to design … Webb23 apr. 2024 · Diffusion and Osmosis. Osmosis is a selective diffusion process driven by the internal energy of the solvent molecules. It is convenient to express the available energy per unit volume in terms of “osmotic pressure”. It is customary to express this tendency toward solvent transport in pressure units relative to the pure solvent. Osmotic ...
