In this work, an atmospheric model combustion chamber was characterized employing Laser Vibrometry, chemiluminescence and Particle Image Velocimetry. The test object was a variable geometry burner enclosed with a liner, with the flame optically accessible through four fused silica windows. In this burner with adjustable flame conditions the cavity of the atmospheric model combustion chamber was excited at a frequency around 200Hz. Resonant and non-resonant flame conditions were investigated and compared by laser vibrometer interferometry, schlieren visualization and OH*/CH* chemiluminescence. Additionally, the velocity field was recorded with Particle Image Velocimetry, while the aerodynamics of the burner plenum was analyzed with Computational Fluid Dynamics.

Digital Particle Image Velocimetry (DPIV) currently represents the state of the art for non-invasive global flow velocity measurements. The instantaneous velocities are determined by cross-correlating patterns of particles between consecutive images, thus mapping in space and time the velocity distribution for thousands of points in the flow field simultaneously.

Currently, an echo particle image velocimetry (ePIV) system for the investigation of in vivo blood flow and shear stress is under development at the University of Calgary. To date, encouraging preliminary results have been obtained when comparing ePIV derived velocities to analytical solutions. However, large discrepancies were noted between our steady state ePIV derived velocities and velocities measured using pulse wave Doppler (PWD). Ultrasound beam thickness, off axis centerline measurements and PWD angle of interrogation likely account for the differences observed.
