However, soot formation involves not only the chemical reaction in the gas phase but also the dynamics of soot particles, which makes the formation process complex. In our laboratory, MOMIC, a modeling method of soot formation, is used to obtain a knowledge on the formation process from the a variety of fules.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"722\" height=\"191\" src=\"https:\/\/www.mech.kyushu-u.ac.jp\/~esl\/HP2021Ver\/wp-content\/uploads\/2022\/04\/\u56f34.png\" alt=\"\" class=\"wp-image-352\" srcset=\"https:\/\/www.mech.kyushu-u.ac.jp\/~esl\/wp-content\/uploads\/2022\/04\/\u56f34.png 722w, https:\/\/www.mech.kyushu-u.ac.jp\/~esl\/wp-content\/uploads\/2022\/04\/\u56f34-300x79.png 300w\" sizes=\"auto, (max-width: 722px) 100vw, 722px\" \/><figcaption>Fig. 2 Growth process of soot<\/figcaption><\/figure><\/div>\n","protected":false},"excerpt":{"rendered":"<p>\u30fbSpontaneous ignition of droplet pairs \u3000In addition to the experiment, numerical investigation on the spontaneous ignition behavior of droplet pairs is being conducted in our laboratory.
