- Abstract
- A theoretical and experimental study of the structure and radiation properties of turbulent diffusion flames is described. Generalized state-relationship correlations, giving the mass fractions of major gas species (N2, O2, fuel, CO2, H2O, CO and H2) as functions of local fuel-equivalence ratios, were developed for hydrocarbon/air diffusion flames. Instantaneous soot volume fractions and temperatures were measured in the fuel-rich (underfire) region of turbulent nonpremixed acetylene, propylene, ethylene and propane flames burning in still air.
