Papers by Keyword: Two-Phase Swirling Flows

Abstract: For precise hole surfaces, the burr severely affects products’ performance and service life. Considering specific conditions of hole surface finishing, a new method of gas-particle two-phase swirling flows finishing is brought up. By experimental analysis, finishing effect and axial uniformity are defined, which provides credible basis for thorough research, equipment design and industrial application.

Abstract: For the precise hole surface, the burr severely affects products’ performance. Considering the specific conditions of the precise hole surface finishing, a new method of gas-particle two-phase swirling flows finishing is brought up. By theoretic analysis, equipment parameters, nozzle angle, nozzle diameter, nozzle quantity, nozzle displacement, etc., affect finishing quality and efficiency. Numerical simulation of equipment parameters is done through CFD software (Fluent, Gambit), which provides credible basis for thorough research and equipment design.

Abstract: Two-phase swirling flows finishing is put forward mainly for hole surface. By theoretic analysis and experimental research, the characteristics of flows field will directly affect finishing quality and efficiency. On the basic premise of defining Renault stress model on swirling flows field, numerical simulation of velocity vector graph, turbulent kinetic energy graph, turbulent dissipation ratio graph, pressure distribution graph, vorticity magnitude distribution graph etc. are made, and vorticity magnitude and tangential velocity in different mediums are contrasted, which provide theoretic basis for thorough research.
