In this study, ECDM was used for the processing of honeycomb seal structures, and fluid dynamic simulation and experimental study were conducted. A vortex effect was observed, hindering the electrolyte flow. Compared to other fluid supply methods, a bilateral fluid supply can reduce vorticity and velocity, weakening the vortex effect. According to the result and the current signals after discrete wavelet transformation (DWT), the higher voltage and flow ...
