界面活性剤注入による抵抗低減乱流境界層流れにおける大規模乱流構造の PIV 計測

抄録

In this study, we conducted PIV measurements for a turbulent boundary layer with nonionic surfactant solution injection from wall surfactant at the momentum thickness Reynolds number up to 1500. The nonionic surfactant, which mainly consists of oleyldimenthylamineoxide (ODMAO), was used. Turbulence structures were investigated for water and surfactant injection flows.
