碩士 === 國立成功大學 === 航空太空工程學系 === 105 === In this study, we use the commercial software, ANSYS CFX, to simulate the flow fields of the electrochemical machining(ECM). The main objective is to analyze the parameters in ECM. In the simulation, we used a high order scheme and K-Epsilon turbulence model to solve the incompressible Navier-Stokes equations coupled with electromagnetic sources. The grid system used is a unstructured grid system generated by ICEM CFD. First, three test cases, three-dimensional cavity, three-dimensional curved pipe, and Aluminium matrix composites using Multiphysics simulation, are simulated to demonstrate higher simulation accuracy. Then the Aluminium matrix composites using Multiphysics simulation is investigated. Finally, the effect of processing voltage, material of the tool, conductivity of the electrolyte, and interelectrode gap(IEG) on the flow field are investigated.
