The wind tunnel team at Sandia National Labs continues this year to advance its time-resolved particle image velocimetry, or PIV capability using a pulse-burst laser. In its most recent configuration, measurements have been achieved at an astounding 400 kilohertz though restricted to a small field of view--which therefore has been dubbed "postage-stamp PlV." More than 4,000 sequential vector fields can be acquired. This unprecedented framing rate is well-suited to measuring turbulent velocity spectra in high-speed flows and is being used to improve the physical models underlying aerodynamic simulations.
