Abstract:

This grant supported the purchase of volumetric particle-image velocimetry PIV equipment that provides data acquisition in the kilohertz kHz range over volumetric fields of view for time resolved studies of the dynamics of complex turbulent flows, particularly on-going studies of realistic roughness effects in wall turbulence AFOSR core grant FA9550-14-1-0101. While existing PIV equipment in the PIs lab provides extremely high spatial resolution for measurements of moderate Reynolds number turbulent flows, it does not afford similar resolution in the temporal domain, nor the ability to measure 3D aspects of these flow fields. Therefore, the equipment acquired with this funding was specifically selected to expand our capabilities in both of these domains to provide a step-change in our ability to interrogate complex, and inherently 3D, turbulent flows of relevance to a range of DOD applications.
