Abstract

This work will mainly focus on the design, construction, and installation of the Particle Image Velocimetry (PIV) system in the Chemical Hazards Research Center wind tunnel. The PIV system utilizes a Class IV (double pulsed) laser, optics to produce a light sheet, timing circuitry, and a high-resolution camera (with buffered output) to measure a system’s velocity (two-dimensional) field by determining the displacement of particles over the time between laser pulses. For maximum mobility and functionality, the PIV system was installed in the center of the tunnel on a moveable cart with the laser and camera mounted to an adjustable support. The instrument support will allow for a variety of obstacle configurations to be studied. Based on the conditions during a recent set of field dispersion trials, basic experiments were performed to demonstrate the viability and versatility of the system. These experiments discussed here consider the fluid dynamics directly behind three different (model) CONEX containers.
