Active Control of Turbulent Boundary Layers for Drag and Noise Reduction in Naval Applications

Abstract

Lorentz Force actuators were developed and characterized. They were used to measure the effect of lorentz force control on the drag of a fully turbulent channel flow. Approximately 15% drag reduction was achieved
