We develop hardware and software for novel measurement techniques, focusing mainly on the small scale structure of turbulence. We design and develop miniature flow sensors based on fluid-structure interactions, three-dimensional particle tracking velocimetry with real-time image processing, and novel flexible structure viscometers.
Our main research interest is the structure of turbulent flows in natural and industrial applications. Our speciality is in accurate measurements of velocity derivatives in Eulerian and Lagrangian settings, using either multi-hot-wire or micromachined sensors or 3D particle tracking velocimetry (3D-PTV) technology. We also implement our methods to unsteady flows (pulsating, periodic, etc.) of gases and liquids in electronic cooling applications, semiconductor industry applications (coating, etching, vacuum,s etc.), bio-medical applications and resuspension of particulate materials from smooth and rough walls.
