Harvesting low-grade heat energy using thermo-osmotic vapour

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. WebbThermo-osmosis is a coupled phenomenon describing the fluid flow induced by a thermal gradient. Recent studies on thermo-osmosis in clays and within the coupled thermal, hydraulic and mechanical analysis have revealed the importance of this physical processes in geo-energy and geo-environmental applications. thelma ice cream
