Project Description

The purpose of this project was to develop a safe, efficient, and repeatable RDE testing procedure, building confidence in the procedures to allow for the analysis of design changes in future fundamental studies. Changes in procedural order in addition to the expansion of safety information and labeling allowed for an efficient testing process. Six successful detonations were performed, with tests concluding after multiple satisfactory and repeated results were observed, supporting the efficacy of the refined testing procedure. The current visual acquisition method introduced inconsistencies with data gathering, so in order to obtain accurate visual flame measurements, the camera setup will be altered to improve repeatable data collection for future detonations. A separate experimental setup was designed to produce an atomized spray of water with the option to interchange nozzles of different orifice diameters. This atomized water spray is to allow testing of standard operating procedures for the multispectral highspeed infrared camera that will be used with the RDE in future studies. As the scope of the project expands into analyzing fuel injection methods, the procedure will be expanded to include additional content and uncertainty estimation of results.
