Biomimetic Riblets Inspired by Sharkskin Denticles: Digitizing, Modeling and Flow Simulation

While sharkskin surface roughness in terms of denticle morphology has been hypothesized but remains yet controversial to be capable of achieving turbulent flow control and drag reduction, sharkskin-inspired “riblets” have been reported to be an effective biomimetic design. Here we address an integrated study of biomimetic riblets inspired by sharkskin denticles by combining 3D digitizing and modeling of “fresh” denticles and computational fluid...
