On the effects of tangential air inlets distribution configurations to the combustion characteristics of a direct injection liquid fueled swirl flameless combustor (SFC)

Liquid fueled flameless combustion is a new niche in the energy-engineering department. The current trend on flameless combustion is mostly focused on gas fuel application due to the ease of achieving and maintaining flameless mode in the combustion process. The main purpose of this paper is to disc...
