Effects of Materials and Riblets on Erosion Mitigation Induced by Multiple Collapses of Cavitation Bubbles

Applied Sciences
The current research investigates the effects of materials and riblets on cavitation-induced erosion morphology, depth, and cross-sectional area through experimental approaches. To achieve these aims, the erosion of pure aluminum (1xxxAl or Al) and alpha

Impact of groove filling due to particle accumulation on the drag reduction performance of riblets in turbulent channel flow

Journal of Fluid Science and Technology
This study aims to clarify particle adhesion characteristics on riblet surface using direct numerical simulations and experiments. Numerical simulations of particle-laden, fully developed turbulent channel flow with rectangular riblets were performed to ...
