Multi-Port Hele-Shaw Cell for Scalable Mesh Pattern Formation: Anisotropy-Driven Fluid Shaping for Microfluidic Applications

Abstract The introduction of a multi-port Hele-Shaw cell setup presents a novel approach to exploring viscous fingering patterns. This study investigates fluid interactions influenced by anisotropies in material properties and experimental configurations. By varying hole diameters, groove dimensions, fluid viscosities, and lifting velocities, distinct mesh patterns were generated. The research demonstrates a cost-effective alternative to lithography for applications in microfluidics and biomedical engineering. Detailed analysis shows that hole and groove dimensions, coupled with controlled airflow, are pivotal in determining pattern uniformity. The findings offer critical insights into fluid shaping processes, emphasizing their potential for scalable fabrication.
