Outline of Final Research Achievements

In order to clarify the drag-reducing mechanism for the case of the turbulent boundary layer flow at the high-Reynolds number following the injection of the surfactant solution, we performed the flow visualization, LDV and PIV measurements of turbulent boundary layer flow, the DNS of turbulent channel flow with new constitutive equation model (BMP-G model), and rheological measurements based on transient property of uniaxial elongational flow.
