Experimental Data Acquisition and Quantitative Visualization of Turbulent Jet Mixing Layers

Abstract

This AFOSR/DURIP sponsored funding was used to upgrade the data acquisition, graphics and image processing capabilities of the Turbulence Research Laboratory (TRL) of the State University of New York at Buffalo. The proposed upgrades were of immediate benefit to the research sponsored by AFOSR (Investigation into the Dynamics of the Jet Mixing Layer) as well as a number of on-going and anticipated investigations. The AFOSR sponsored effort enhanced on-going research using 138 hot-wire probes to investigate the dynamics of the jet mixing layer. The hot-wires are used to obtain simultaneous data at 138 positions so that the instantaneous velocity profiles can be reconstructed using the proper orthogonal decomposition (POD). The complexity of the data acquisition required for this number of probes has been considerably simplified. In spite of this, the demands on the data acquisition system and the experimenter are enormous, especially with regard to calibration and post-data-acquisition validation, visualization and processing of the data. The equipment purchased both addressed the immediate research needs, and considerably enhanced the ability of the Turbulence Research Laboratory to meet the needs of the university and regional technical community.
