Turbulent JP-8 Flames: Concentration and Temperature Profiles to Assess a Chemistry Mechanism

Abstract

The objective of this effort is to study turbulent flames with vaporized JP-8 (and butane) fuel and measure the profiles of 14 important chemical species and gas temperature at AF jet engine conditions. These profiles will be provided to Stanford researchers to assist them in the development of their improved reduced-chemistry mechanism of JP-8 fuel. Also, we will measure and vary the chemical residence time. This is the time for a fluid element to cross the three reaction zones. It is proportional to flame thickness divided by normal velocity. The advantage of turbulent flame experiments at high Reynolds number is that they provide the correct residence times associated with jet engine combustors and augmenters, so this work will complement other work, including shock tube studies.
