High-Fidelity PIV of a Naturally Grown High Reynolds Number Turbulent Boundary Layer

ORAL

Abstract

High-fidelity particle image velocimetry data acquired in the the Flow Physics Facility (FPF) at the University of New Hampshire is presented. Having a test section length of 72m, the FPF employs the ``big and slow'' approach to obtain well-resolved turbulent boundary layer measurements at high Reynolds number. We report on PIV measurements acquired in the streamwise---wall-normal plane at a downstream position 59m from the test-section inlet over the friction Reynolds number range $7000 < Re_\tau < 15000$. Local flow tracer seeding is employed through a wall-mounted slot fed by a large volume plenum located 13.4m upstream of the PIV measurement station. Both time-independent and time-dependent turbulent flow statistics are presented and compared to existing data.
