High-Speed Digital-Image Data Acquisition, Processing, and Visualization System for Turbulent Mixing and Combustion

Abstract

This report summarizes an equipment and instrumentation system for high-speed digital image data acquisition and processing. The research program targets the physics of turbulence, mixing, and combustion, focusing on high-speed environments. The system includes components for Planar Laser Induced Fluorescence (PLIF), flame-speed, and ignition and extinction measurements of laminar flames at variable pressure; tracking flow structures in a high-speed mixing layer using high-speed color schlieren; laser-beam manipulation and volume scanning for three-dimensional turbulence measurements; and an expanded infrastructure capability for processing experimental and numerical-simulation data.
