Experimental aspects of soot presence in pulsating diffusion flame

the present paper shows experimental results about soot suppression on a laboratorial scale jet free diffusion flame of liquefied petroleum gas submitted to acoustic oscillations. the experiments were conducted to verify the influence of amplitude and frequency of oscillations in the regions of soot formation and suppression through the flame. to quantify the soot presence the laser induced incandescence was utilized. the results show combinations of frequency and amplitude of oscillation which the presence of soot is close to zero.
