A Model of the Flow of a Nanomedium Removing Particles from the Electroerosion Zone

A model was proposed and studied to explore the changes in the dynamics of the physical properties and structure of a homogeneous medium in the anode-cathode (SWCNT-surface) gap due to the influence of stochastic emission of erosion particles into the random interval during their carryover by the medium from the electroerosion zone during making micro- and nanoholes in the material. The model takes into account the influence exerted on the properties of the combined flow by the dynamics of the motion of a tool (SWCNT-electrode), the orientation of the erosion zone and particle removal, and the variable density of the homogeneous phase of the flow. Changes were identified in the properties and parameters of the combined flow during the carryover of its erosion particles at different angles of orientation of the erosion zone. Verification using the methods of similarity theory and practice showed satisfactory agreement between the modeling results, numerical experiments, and natural experiments conducted by other researchers.
