A novel technology to reduce soot is developed utilizing a high-frequency standing wave of 20 kHz applied to a methane-air lifted jet flame base. The amount of soot was measured using the transmitted light attenuation method. A mixing profile of the fuel jet was visualized using acetone planar-laser-induced fluorescence in order to measure the mixing status when the ultrasonic wave wa... https://www.hindirochakkahaniya.com/
