Abstract

: In the context of monitoring these physical systems, the S_Dbw (SDBI) cluster validity index is often employed to evaluate the performance of image segmentation algorithms used to track fluid particles. It measures the scattering and density of clusters to ensure high-fidelity data extraction from high-speed video. 3. Methodology dve_sdbi

Active flow control has seen significant advancement through the use of plasma and EHD actuators. have gained prominence due to their ability to sustain high voltages via dielectric barriers, which prevents direct arcing and allows for controlled charge injection into non-conducting fluids like silicone oil. This paper investigates the transition between homocharge and heterocharge regions and their impact on vortex formation. 2. Theoretical Framework Abstract : In the context of monitoring these

: Evaluating the effect of square-wave signals, duty cycles, and frequencies on jet velocity. 4. Results and Discussion

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
