摘要: Overventilated, coflowing axisymmetric laminar diffusion flames of ethylene, propane, and butane were used to study the influence on soot hydrogen addition fuel. The flame temperatures measured by CARS along axis as well at off-axis radial locations. spectra taken in heavily sooting regions exhibited poor fits due C 2 absorbtion part fundamental band nitrogen spectrum. It was found that confined frequencies greater than 2313 cm −1 . We, therefore, implemented a strategy fitted only frequency range smaller Measured concentrations temperature data with without helium dilution evaluated relative influences direct chemical interaction formation, result addition, are presented. is shown when or added fuel diluent moderate quantities, changes field coflow negligible. When allowance made for dilution, side an ethylene reduces formation. For propane flames, does not show any formation apart from effect.
