Bio-Inspired Hydrodynamic Boundary Layer Control

Design a scale-model hull geometry that utilizes active or passive surface texturing to induce turbulent transition delay and minimize skin friction drag. Evaluate the efficacy of your design by measuring the flow velocity differential across a closed-loop recirculating tank versus a baseline flat-plate control model. Provide a technical brief analyzing the Reynolds number regimes where your texture geometry achieved peak drag reduction.
Materials: Polyvinyl chloride sheets, waterproof adhesive, 3D printing filament, non-toxic micro-beads for flow visualization, variable speed pump.
