Temperature, velocity, and nox/co emission measurements in turbulent flames: effects of partial premixing with central fuel injection

DNS analysis of partially premixed combustion in spray and gaseous turbulent flame-bases stabilized in hot air

“…The results of these works suggest that premixed and diffusion burning modes may be very closely located in space and strongly coupled in terms of chemistry and transport. In turbulent flows, partially premixed combustion was 0010 first investigated in jet flames [7,8]. A quite obvious configuration where partially premixed combustion plays a crucial role is the turbulent jet flame lifted off the burner exit.…”

In-situ diagnostics of chemically reacting flows using laser-induced breakdown spectroscopy

“…5. The flame conditions are for partially-premixed turbulent flames using methane-air mixture [21]. Again, there is quite a good agreement between the two different methods, and indeed LIBS exhibits the temperature profile expected of turbulent jet flames.…”

Temperature measurement of axisymmetric partially premixed methane/air flame in a co-annular burner using Mach–Zehnder interferometry

“…Air and fuel are mixed in a mixing chamber filled with stainless steel beads to assure a complete mixing. The distance between mixing chamber and burner is long enough to ensure homogeneity of methane/air mixture [24]. The flow rate for each gas is adjusted using pre-calibrated Dwyer flowmeters and pressure gauges.…”
