- A key component of advanced combustor design is the recirculation, or back mixing, of hot combustion products with incoming fuel and air. Experimental and numerical research efforts at Berkeley have focused on the design of simple jet flame configurations that target the strong codependence between the turbulence and chemistry inherent in combustion with recirculation. Previous studies have only focused on jet flames with a coflow of air. A simple coaxial jet with vitiated coflow emanating from a turbulent, premixed flame is currently under development at the Berkeley laboratory. The burner consists of a jet at the center of a flame stabilizing, perforated plate. Once the burner design is refined, constructed and characterized, it will be transported to the nearby National Combustion Research Facility at Sandia National Laboratories in Livermore where laser diagnostics will be performed.
