Abstract

Abstract: The design of flow field is an important part of preparing the cathode and device in the electrochemical machining of cochlear channel of closed integral structure. The models of the forward feed device and reverse feed device are established based on UG , of which inlet area is about twice as much as outlet area，respectively, and their gap flow fields are simulated based on COMSOL Multiphysics. The difference between these gap flow fields formed by the forward feed and reverse feed at the same electrolyte inlet pressure is analyzed from its streamline pattern, velocity and pressure nephograms. The results show that the flow velocity of the end gap and the side gap in the reverse feed is higher than that in the forward feed, and the flow field of the reverse feed is more uniform. The reverse feed devices are used in the experiment, the machining process is smooth without spark and short circuit.
