Instrumentation for Turbulent Reacting Flows
Abstract
The design and technical capabilities of the following systems are described: (1) Copper Vapor Laser pulsed light source with spatial filter and collimator.(2) Proximity focussed diode intensified linear CCD camera. (3) High speed multiplexed Analog to Digital Conversion system. (4) Monochromator system for point or line imaging of chemiluminescence. This instrumentation has been assembled to exploit several nonintrusive optical techniques to make measurements in a wide range of turbulent flows. The primary, but not exclusive, measurement technique to be implemented was Rayleigh scattering, imaged along a line as a function of time. A slightly modified version of the same apparatus was to be used in performing scattering measurements or (liquid-phase) laser- induced fluorescence measurements with the same temporal and spatial resolution capabilities. A second technique was to make use of a monochromator to analyze, and possibly image, chemiluminescence in a reacting flow in a wavelength- specific fashion, either at a point or along a line. The light source, the detection systems, and the data acquisition systems assembled under this funding will each be described.
