Abstract

This paper presents the experimental and numerical study of laminar lifted flames of methane diluted with nitrogen in co-flow jets. Liftoff height characteristics of such flames were observed with the variation of fuel nozzle exit velocity. These lifted flames show the decreasing liftoff height behavior by increase of fuel nozzle exit velocity (at low nozzle exit velocity). Schmidt number for these flames was less than unity. This study is fully focused on lifted flames with decreasing liftoff height behavior only. From numerical simulations it was clarified that under normal gravity the buoyancy convection could be the reason for such decreasing liftoff height behavior of lifted methane jet flames.
