: Applying the S_Dbw index to the experimental video results confirmed that the clustering of velocity vectors was statistically sound, with minimal quantization error. 5. Conclusion Coupling characteristics of fluid and charge behaviors in

: Experimental and simulation data suggest that a square wave signal (specifically at 0.2 Hz for certain silicone oil viscosities) proves most efficient for generating high-velocity flows. Conclusion : Experimental and simulation data suggest that

: SDBI operates through the dissociation of charges and subsequent injection into the fluid medium. Simulation results indicate a homocharge region forms at the electrode tip, while a heterocharge layer builds on the upper surface.

This paper explores the mechanics and coupling characteristics of actuators, specifically focusing on the generation of electrohydrodynamic (EHD) wall jets. We analyze how charge injection, migration, and accumulation at the dielectric surface influence flow structures under various pulse signals. Using finite element methods, this study identifies optimal electrical parameters for high-velocity silicone flow, with implications for microfluidics and aerodynamic control. 1. Introduction
