For that purpose, experiments are conducted in a statistically steady turbulent pipe flow, ramp-type accelerating/decelerating turbulent pipe flow and turbulent Taylor-Couette flow. For the first two flows, time-resolved data is acquired in the cross section of the pipe with stereoscopic PIV. The databases spanning over a friction Reynolds number range of Re⌧ = 340−1259 are utilised to study coherent motions, in particular the large-scale motions and the internal shear layers bounding them. For the turbulent Taylor-Couette flow study, in addition to torque measurements, high resolution stereoscopic-PIV measurements are performed in the radial-axial planes to investigate the hysteresis phenomenon in the system.
