Test of long-term stability carried out on the synthesized organic-inorganic NF-PANZr membrane under test conditions: cross−flow rate = 30 L·h−1cross−flow rate = 30 L·h−1; pH=6pH=6; [MgCl2] = 1000 mg/LMgCl2] = 1000 mg/L, 168 h test; pressure = 0.6 MPa0.6 MPa. ...
Mixed electroosmotic/pressure driven (EO/PD) flow of power-law fluids in microchannels and micropumps is analyzed using a numerical scheme based on the finite volume formulation. Effects of the fluid behavior index (n), zeta potential and electric double layer (EDL) thickness are investigated on...
Experimental and Numerical Study on the Seismic Response of a Surface Frame Structure–Soil–Double-Tunnel System The interaction mechanisms of the underground tunnel passing through the surface structure for a short distance are complex, and there are hidden dangers, ... R Ma,Q Cao,S Lu,... ...
This comparison shows that the concentration dependence of the viscosity, diffusivity and osmotic pressure are all necessary to explain experimental results published in the literature.doi:10.1016/j.desal.2009.05.012A. AfonsoJ.M. MirandaJ.B.L.M Campos...
However, because of the uncertainty on the value of the shale pore radius, additional head measurements and osmotic experiments on samples should be made to fully establish the possibility of an osmotic process. Our study also shows that recent changes in hydrodynamic boundary conditions could also ...

The interfacial membrane allows transmembrane water flow which is determined by osmotic and mechanical pressure differences across the membrane. The numerical method is based on an immersed boundary method for fluid-structure interaction and a Cartesian grid embedded boundary method for the solute. We ...
osmotic dehydrationbiological tissuesmathematical modelIn this paper a mathematical model based on mass transfer in plant tissues is developed. The model takes into account the diffusion and convection of each constituent within the tissue. The driving force for the convection is assumed to be the ...
Based on this understanding, this study proposes a chemical osmosis experiment for screening reservoir rocks that can potentially improve oil recovery by potential transfers. An oil-free porcelanite with 11 wt% clay content showed that osmotic pressures greater than 10 kPa were established at the ...
