MEASUREMENT OF WETTING CORNERS ON THE BORDER ICE - WATER - OIL
The measurment of balanced edge corners of wetting of flat surfaces by two not mixing up liquids requires the program Angle application to process the image of system: a drop - a substrate - environment. Due to the fact that the researcher who deals with the given program defines only a point into which the line of three-phase contact on a plane is projected, and all the rest is carried out automatically, the error of measurement does not exceed 1 %. The technique of preparation of ice samples with suitable for measurement surface is given. Results of measurement for samples of oil from deposits Rechitsa (Belarus) and Surgut (Russia) are presented, which show, that because of bad wettability in case of oil pipeline rupture, oil under water will slide between ice and ice surface.
