The emission of soot and thermal radiation by free turbulent diffusion flames of CO, H 2, Cl-b,, C2H 6, Calls, C2H4, and C2H 2 was studied over a range spanning the transition from forced convection to natural convection (burner diameters 0.7-10.9 mm, buoyancy Richardson ratios Ri L ~ lrgpcx~L3/4Go
Emission profiles and spectra in the visible, uv, and ir have been measured in quasi-premixed, flat C2H2-F2 flames at 7.0 mbar. The bands observed were those of C2, CH, and C3. In addition, three distinct continua have been observed which can be attributed to CF~, C3, and to polymeric species. The o
Numerical simulation with detailed chemistry has been carried out to clearly discriminate the thermal and chemical contributions of added diluents (H 2 O and CO 2 ) to major flame structures and NO emission characteristics in H 2 /N 2 counterflow diffusion flame. The pertinence of GRI, Miller-Bowman
