Investigation on the flow field of W-shape electrolyte flow mode in electrochemical machining

A new W-shape electrolyte flow mode was developed to improve the blade accuracy and surface quality in electrochemical machining. Its mathematical model in the interelectrode gap was obtained as equations of such main flow parameters as the pressure, channel width, volumetric gas-phase concentration, velocity, and temperature. According to the model, the distribution of the flow field was simulated. Subsequently, experiments were carried out so as to validate the W-shape electrolyte flow mode and its mathematical mode. The results proved that the mathematical model was correct, the flow mode was reasonable, and the accuracy and surface quality of blade were enhanced greatly.
