The amounts of chloroform-soluble material, polycyclic aromatic hydrocarbons (PCAH) and cvrbonaceoas residue in the dry soot recovered from ethylene-air and ethane-air diffusion flames respectively have bcea determined and t he effects on these of incseasing additions of oxygen to the fuel have been
Soot measurements were made in laminar ethylene diffusion flames for various fuel and air flow rates in a Wolfhard-Parker burner. Simultaneous light scattering and extinction measurements yielded spatially resolved particle number densities, particle size, and soot volume fraction. Laser doppler vel
Measured soot volume fraction profiles are combined with the modeled temperatures, velocities, and mixture fractions in an axisymmetric laminar diffusion flame to derive local soot formation rates. The flame is modeled by solving transport equations for momentum, mixture fraction, and enthalpy toget
Profiles of soot concentration together with gas species concentrations and temperature are measured in propane/air turbulent diffusion flames of two typically different air inlet temperatures of 50 and 500Β°C, paying special attention to the roles of gas temperature on the behavior of soot formation
