FIELD: mechanical engineering. ^ SUBSTANCE: invention relates to method of action onto rheological properties of fluid medium which is in contact through boundary surface with at least one corresponding part of plant or machine. According to proposed method, fluid medium is suspension, and vibrations of different elements of fluid medium are excited selectively and at least one boundary surface has vibration component square to tangential plane of boundary surface of wall/fluid medium. According to other version, fluid medium is polymer or mixture of polymers, and vibrations of different elements of fluid medium are excited selectively also, and at least one boundary surface has vibration component in tangential plane of boundary surface of wall/fluid medium. ^ EFFECT: provision of purposeful action onto rheological properties of fluid medium for reduction of friction of fluid medium against boundary surfaces of fluid medium/machine. ^ 78 cl |
