Imaging diagnostics for in situ measurements within challenging environments
Abstract/Contents
- Abstract
- The development, validation, and deployment of imaging diagnostic systems and corresponding image processing algorithms are presented that enable in situ measurements within two challenging environments: aquatic environments and high temperature, high pressure reactive gas environments. Image processing algorithms for a single-camera defocusing digital particle image velocimetry (DDPIV) imaging system were developed to perform three-dimensional tracking of natural particulate and organisms in the water column within a 10 cm x 10 cm x 20 cm volume at 60 Hz. The developed underwater imaging system was deployed at the Marine Biological Laboratory (Woods Hole, MA), and measurements of Mnemiopsis leidyi ctene rows are presented to demonstrate the measurement capabilities of the developed system. An imaging diagnostic was developed to image the structure of combustion events behind reflected shock waves. An intensified high-repetition-rate imaging system was used to acquire images of OH* chemiluminescence (near 308 nm) through a fused quartz shock tube end-wall window at 10-33 kHz during the combustion of n-heptane. The imaging technique enabled observation (12 cm x 12 cm) of the main ignition event in the core of the shock tube, that corresponds to typical markers of ignition (e.g., pressure rise).
