Experimental study on premixed flame combustion of annular burner with CO2 dilution based on OH-PLIF technology

In view of the combustion characteristics of annular chamber of micro gas turbine, a planar laser-induced fluorescence (PLIF) technique was used to investigate the methane/air premixed turbulent multiple flames in the annular combustor and the effect of CO2 on the characteristic parameters of flame...
