Abstract

The behaviour of methane jet flames autoigniting in a turbulent cross-flow at MILD combustion conditions was examined experimentally. The methane jet was injected orthogonally into a turbulent, low oxygen (XO2x<8%) cross-flow at high temperatures in a cylindrical quartz tube. Regardless of cross-flow conditions, the methane jet autoignited and a flame was stabilized in a wide region clearly separated from the injection nozzle. OH∗ chemiluminescence images show that OH∗ intensity was not significantly diminished by changing XO2x, but the size of the reacting region, as well as its location, was noticeably sensitive to XO2x. Cross-flows enriched with additional air sustained methane jet flames with larger reactive regions than those diluted w...
