Investigation of Rough-Wall Turbulence Over Barnacle Roughness

Explore the intricacies of rough-wall turbulence over barnacle roughness in this 31-minute conference talk presented by Sotirios Sarakinos and Angela Busse from the University of Glasgow. Delve into their research, recently published in Physical Review Fluids, which investigates the influence of barnacle-type rough surfaces with increasing coverage on wall-bounded turbulence. Learn about their direct numerical simulations of turbulent channel flow, where rough surfaces were generated using an algorithm mimicking barnacle settlement behavior. Examine the evolution of barnacle fouling across seven different surfaces, ranging from lightly fouled (10% coverage) to fully covered (85% coverage). Gain insights into marine biofouling, the barnacle algorithm, rough surface characteristics, and the blanketing layer. Participate in a live question-and-answer session moderated by Adrian Lozano Duran from MIT, where all attendee questions will be addressed.
