RHEOLOGICAL FEATURES OF LIQUID IN MICROCRACKED CHANNELS WITH THE “MICROCRACK-LIQUID” EFFECT DISPLAYED
Based on experimental and theoretical studies in plane-radial and plane-parallel microcracks, a previously unknown pattern called “microcrack-liquid” effect was established for the first time, that when viscous liquids move in a microcrack at hhcr these effects disappear.
It was revealed that the reason for the manifestation of anomalous properties of Newtonian liquids and the enhancement of the rheological properties of non-Newtonian systems when they move in microcapillary cracks is the new microcrack effect of the “microcrack-liquid” system.
The established critical values of crack opening for the studied viscous oils are 160 μm at a temperature of 303 K.
Keywords: microcrack opening, non-Newtonian fluids, ultimate shear stress, structural viscosity, microcrack-liquid effect.
