Description

technical field [0001] The invention relates to the technical field of fluid-solid two-phase fluid and abrasive flow processing in mechanical engineering, in particular to a device and method capable of measuring the slip velocity of abrasive grain phase in viscoelastic fluid abrasive grain two-phase flow. Background technique [0002] In the field of abrasive flow machining (Abrasive Flow Machining, AFM), the fluid phase is a fluid polymer material with high viscosity, which is a typical non-Newtonian fluid. Motion, called wall slip, is completely different from the flow velocity of ordinary Newtonian fluid at the wall. Wall slip is an inherent phenomenon in the flow of a large number of non-Newtonian viscoelastic polymer fluids. In the field of abrasive finishing, fluid abrasives composed of viscoelastic fluid and abrasive grains are used to smooth closed areas such as inner holes of curved pipe fittings or small slits, which is driven by the wall slip characteristics of v...
