Abstract

In support of ongoing investigations into turbulence generated aero-optic effects, Teledyne Brown Engineering (TBE) has conducted a series of laboratory based experiments on high velocity turbulent mixing/shear layers. The cornerstone of this effort was the TBE designed and fabricated Dual Injection Nozzle Aero-Optic Simulator for Endoatmospheric Research (DINASER). The DINASER was used to generate flow conditions that simulate the aero-optic effects encountered in flight. The goal of the investigation was to collect data that could be used to validate computational fluid dynamic (CFD) codes, evaluate turbulence models, and anchor aero-optic propagation codes, all of which are essential components in flight simulations. From previous experiments and analysis, the unknown quantities necessary to validate the turbulence models and CFD code have been separated from the essential optical quantities. This investigation has primarily focused on the quantification of the optical parameters, measured along the line-of-sight.
