Abstract
In order to study the temperature regularity of inter-electrode gap in PECM, the multi-physical coupling model based on COMSOL Multiphysics platform is established. The model of blades was used for this study, and the impact of some factors on the temperature is analyzed. The results show that the duty ratio is smaller or the inlet pressure is greater, the process of electrolyte convective and heat transfer is more sufficient. At the same time, the increase of the voltage and the decrease of the gaps will exacerbate the temperature fluctuations in a single pulse time. The lower voltage and duty ratio with larger inlet pressure should be selected in small gaps of PECM, so that we can effectively avoid the negative influence of high temperature in the processing zone.
