Vortex Dynamics in 2-dimensional Soap Film Turbulence

Jun 09 2020 Physics Course Project Group Work Fluid Dynamics Experimental Physics Data Analysis PIV method

Soap films form a quasi-2D fluid system with multi-scale vortices. Driven by electric fields, they exhibit complex turbulent behaviors. This study aims to observe how small boundary vortices evolve and merge into larger structures, and to analyze the spatiotemporal dynamics of soap films with varying geometries. Read More
