Abstract

Flow separation is a major factor in the form drag experienced by a moving object. In particular, suppressing or reducing flow separation is critical in the reduction of energy expenditure of autonomous underwater vehicles. Previous research suggests that bio-inspired micro-fibrillar structures are capable of reducing the boundary layer separation in a turbulent flow. Here, we present laboratory measurements using particle tracking velocimetry near the wall of two submersible vessel models: one coated with an array of micro-fibers and a second one with smooth walls. The flow around the vessels was enticed by the ordered micro-fibers to retain higher velocities near the wall of the vessel. The experiments suggest that separation of the flow may be reduced by the use of the bio-inspired micro-fibers.
