Aeroacoustic measurements and analysis have been made for an unshrouded rotor partially
immersed in a planar equilibrium turbulent boundary layer at low Mach number. This …

Experiments have been performed on the disturbance of a high-Reynolds-number turbulent
boundary layer by three forward steps with sizes close to 3.8, 15 and 60% of the boundary …

This paper presents experimental investigation of upstream roughness and Reynolds
number effects on the recirculation region over a smooth forward facing step. The upstream …

Surface transient storage (STS) and hyporheic transient storage (HTS) have functional
significance in stream ecology and hydrology. Currently, tracer techniques couple STS and …

The pressure fluctuations under a high Reynolds Number, rough-wall, turbulent, boundary
layer have been studied in the Virginia Tech Stability Wind Tunnel. Rough surfaces of …

Measurements of wall pressure fluctuations induced by forward-facing steps with rounded
corners immersed in a turbulent boundary layer were performed. Four different roundings of …

Experiments were carried out in high Reynolds number turbulent boundary layers over
rough surfaces of diverse geometries. Roughness configurations varied in element height …

A new Anechoic Wall Jet Wind Tunnel was built at Virginia Tech. A detailed design based on
the old wall jet tunnel was done to improve the quality of the resultant flow. Aerodynamic and …

The sound generated by a turbulent boundary layer with a smaller two-dimensional step
was investigated and related to the perturbed flow field via a new scaling law. Experimental …

Measurements have been performed to understand the sound source mechanism in
turbulent boundary layer flow over two and three-dimensional surface discontinuities whose …
