Research on Flow Field Simulation and Experiment of Numerical Control Electrochemical Turning

To design the flow field of inner-spraying cathode in NC-ECT, the numerical model was built according to the physical model of the cathode flow channel, and the Computational Fluid Dynamics (CFD) method was applied to solve the numerical model. The velocity and pressure distributions were obtained. The influences of the cathode internal structure on the flow field were analyzed according to the numerical simulation. The relatively good simulation results were obtained by means of the optimization design of the cathode internal structure. Based on the experiment, the accuracy of simulation was verified, and the correction number of the flow field design was reduced in NC-ECT. It is indicated that the CFD method can be applied to guide the optimization design of the cathode structure.
