Experimental investigation of drag reduction in micro-channels with surfaces adsorbed hydrophobic nanoparticles

摘要：

Reconstructing the capillaries and complicated core micro-channels by using the adsorption method with Hydrophobic Nanoparticles(HNPs) can change the properties of walls of micro-tubes and hence decrease the water resistance. It is shown that under the conditions of pressure this can increase obviously the water flux in micro-tubes or microchannels. It is further found that the adsorption method with HNPs can increase dramatically the water phase permeability of core and decrease the water resistance. This is because the HNPs of SiO2 can enhance the hydrophobility of micro-tube walls, which would generate the water-flow-slip effects. This method is of great significance to reduce the resistance in cores micro-channels with complicated structures, and is expected to be a new technology to decrease the water injection pressure of reservoir.
