recommendations! Published in 2018 at "Flow, Turbulence and Combustion"

DOI: 10.1007/s10494-017-9882-2

Abstract: Flame flashback into the premixer is a serious issue in gas turbine combustion, especially for high hydrogen content fuels. Of particular interest is the risk of upstream flame propagation inside the wall boundary layer. Consequently,… read more here.

DOI: 10.2514/1.j065783

Abstract: This paper reports the flashback mechanism observed in hydrogen-enriched flames stabilized in a low-swirl burner (LSB) at atmospheric temperature and pressure. The fundamentals of hydrogen-rich stable flames and spatiotemporal information of flashback phenomena were observed… read more here.
