・Acoustic Excitation
By applying sound waves from a speaker to a jet diffusion flame, the flame shape changes. In our laboratory, we are elucidating the mechanism of acoustic excitation phenomenon through measurement and analysis under various conditions.
・Thermophoresis
In any space where there is a temperature gradient present, small particles move in a strange way. If this movement can be clarified, control of soot particles in combustion engines could be expected.
・Smoldering
Smoldering is a form of combustion which involves a large amount of smoke that proceeds without the presence of a flame. In this laboratory, we are conducting experiments to elucidate the mechanism of smoldering.
・Reignition
In a fire, after extinguishing activities have ended, unburned combustible material may re-ignite. Reignition can be very unpredictable, which makes fireextinguishing activities extremely difficult. In our laboratory, we are studying how to extinguish fires without any risk of re-ignition, and how to prevent the reignition of flammable materials.
