摘要: Abstract Gas temperature measurements have been completed in a lifted propane flame with and without monosized droplets at two radial stations the developing region of jet. A general decrease average gas was observed when were introduced, because local evaporative cooling effects. Profiles rms maxima either side location reaction zone for 5 gaseous flame. Further downstream along centerline, this disappeared jet's fuel-rich central core ceased to exist. The prolonged axial where these double-maxima profiles existed, an extension core. comparison power spectral densities measured suggests that substantially changed flow field region, point enhancing complex vortical structure weakly existent
