Abstract: Studies have been conducted on rheophysical phenomena that occur when a viscous fluid flows through variously opened microcracks. The role of electrokinetic factor in the manifestation of the nonlinear rheological effect in a water flow in a microchannel model – the transformation of a Newtonian fluid into a non-Newtonian one – is examined experimentally. The effect of the electrokinetic potential on the intensity of the mass transfer process in the liquid–microchannel system has been studied based on the plotting of pressure recovery curves (PRC). It is established that by reducing the electrokinetic potential of the system it is possible to significantly enhance mass transfer processes and improving filtration characteristics in microchannels.

Keywords: electrokinetic factor, micochannel, rheophysical phenomena, openness, pressure recovery curves.
