Research: Experimental Evaluation of Bio-Inspired Surface Textures for Drag Reduction i...

Research question: How do bio-inspired surface textures affect drag reduction mechanisms and efficiency in turbulent fluid flows compared to traditional smooth surfaces?

Background & Motivation: Drag reduction in fluid flow has significant implications for energy efficiency in transportation, pipeline systems, and industrial processes. Many natural organisms, such as sharks and dolphins, exhibit surface morphologies that reduce drag and enhance locomotion, inspiring engineered solutions for fluid management.

Research Gap / Question: While bio-inspired textures like riblets and scales have shown promise, systematic studies comparing their effectiveness across different flow regimes and quantifying their impact relative to conventional surfaces remain limited. This project seeks to fill this gap by experimentally evaluating a range of bio-inspired textures under controlled turbulent flow conditions.

Approach & Expected Contribution: The research will involve designing and fabricating test surfaces with biologically-inspired textures using additive manufacturing. These surfaces will be tested in a wind tunnel or water channel to measure drag forces and flow characteristics using high-precision instrumentation. The results will be statistically analyzed to determine the efficacy and mechanism of drag reduction.

Why it Matters: Understanding and optimizing bio-inspired drag-reduction surfaces can enable substantial energy savings and performance improvements in engineering systems. The findings will contribute to the development of advanced materials and surface treatments for sustainable mobility and fluid transport applications.
