Thus, combustion behvaior of the isolated droplet has extensively investigated. In these days, not only an isolated droplet but also droplet pairs and groups have been explored to obtain a knowledge on the interference effects between droplets. In our laboratory, hydrocabon fuels especially focused. Contrary to alcohol fuels, they show cool-flame and two-stage ignition which has large influences on the ignition characteristics in ICE. By using a Michelson interferometer, cool-flame behavior of droplet pairs is being studied.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"467\" height=\"623\" src=\"https:\/\/www.mech.kyushu-u.ac.jp\/~esl\/HP2021Ver\/wp-content\/uploads\/2021\/03\/Spray\u843d\u4e0b\u88c5\u7f6e2.jpg\" alt=\"\" class=\"wp-image-58\" srcset=\"https:\/\/www.mech.kyushu-u.ac.jp\/~esl\/wp-content\/uploads\/2021\/03\/Spray\u843d\u4e0b\u88c5\u7f6e2.jpg 467w, https:\/\/www.mech.kyushu-u.ac.jp\/~esl\/wp-content\/uploads\/2021\/03\/Spray\u843d\u4e0b\u88c5\u7f6e2-225x300.jpg 225w\" sizes=\"auto, (max-width: 467px) 100vw, 467px\" \/><figcaption>Fig. 1\u3000Experimental setup for droplet ignition<\/figcaption><\/figure><\/div>\n\n\n\n<p>\u71c3\u713c\u753b\u50cf<\/p>\n\n\n\n<figure class=\"wp-block-video aligncenter\"><video height=\"540\" style=\"aspect-ratio: 960 \/ 540;\" width=\"960\" controls src=\"https:\/\/www.mech.kyushu-u.ac.jp\/~esl\/HP2021Ver\/wp-content\/uploads\/2021\/03\/\u6db2\u6ef4\u5bfe\u70b9\u706b-1.mp4\"><\/video><figcaption>Fig. 2\u3000Ignition behavior of an n-decane droplet pair\uff080.3 MPa, 650 K\uff09<\/figcaption><\/figure>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Spray combustion has been utilized in the most of internal combustion engines (ICE).
