| Popis: | To gain a more complete understanding of the relevance of laboratory testing to predict fuel stability in advanced jet engine designs, the Navy single tube reactor (STR) was employed to examine the impact of copper contamination on fuel oxidation at fuel temperatures closer to operational limits. Oxygen consumption during autoxidation, in the presence of dissolved copper, was similar in both the STR and the standard jet fuel oxidation test at higher temperatures, although differences in flow rates and residence times were evident. By contrast, copper was innocuous in promoting the formation of thermal deposits at lower temperatures in the STR, up to approximately 170°C, after which rapid deposition occurred. This deposition was accompanied by depletion of copper in the fuel, except in the presence of selected additives. In addition to suppressing oxidation, limiting available oxygen also suppressed copper depletion. The findings of this study indicate that as bulk fuel design temperatures continu... |
