Numerical Simulation of Compulsive Swirling Flows Field on Two-Phase Swirling Flows Finishing

摘要

Two-phase swirling flows finishing is put forward mainly for hole surface. By theoretic analysis and experimental research, the characteristics of compulsive swirling flows field will directly affect finishing quality and efficiency. On the basic premise of defining k-£ model on swirling flows field, numerical simulation of velocity vector graph, streamline graph, pressure distribution graph are made with different characteristic parameter of nozzle number, nozzle spiral lift angle, axes coordinate of the part, original condition of power fountain. Finally simulation result is contrasted with the experimental data, which illustrates the feasibility of the process and provides credible theoretic basis for thorough research.
