The open campus was held in 5-6 August 2022. We opened laboratory with concept of "State-of-the art Combustion Engineering". Graduate students (Master's course) and undergraduate students mainly introduced their research via presentation and also showed the ignition experiment using laser-induced spark and extinction experiment of flame by suction. We sincerely thank all of participants who came our laboratories in both days. We sincerely hope to study with you. There are many contents which could not introduce in the designated period of the open campus. We are welcome you to visit us anytime.
