| Research Abstract |
Although there are many experiments to observe vaporizing or burning fuel droplets as a basic model of spray combustion, the droplets are usually suspended by a fiber in the experiments and the effect of fiber on vaporization cannot be eliminated. This study reports basic experiments of a noncontact droplet suspension method using optical tweezers instead of the suspender. Atomization and observation systems are developed as well as suspension method. As a result, various fuel droplets was successfully suspended by optical tweezers system.
