 Abstract

The drag reduction effect of a semi-circular riblet-structured surface in a turbulent boundary layer is experimentally investigated using the micro-pillar shear stress sensor MPS3. The MPS3 sensor is a novel tool for the quantitative measurement of the wall-shear stress distribution and possesses a high spatial and temporal resolution. The effectiveness and mechanisms of a ribbed surface in skin friction reduction are to be examined in comparison with the flow case of a flat surface.
