In this study, we conducted PIV measurements for a turbulent boundary layer with nonionic surfactant solution injection from wall surface at the momentum thickness Reynolds number up to 1500. The nonionic surfactant, AROMOX, which mainly consists of oleyldimethylamineoxide (ODMAO), was used. First, we compared mean velocity profiles from PIV measurements with those from LDV measurements for confirming the accuracy of the present PIV results. Then, we clarified turbulence structures in the maximum drag reduction region.
