Although there are many experiments to observe vaporizing or burning fuel droplets, the droplets are usually suspended by a fiber in the experiments and the effect of fiber on vaporization cannot be eliminated. Authors propose a noncontact droplet suspension method using optical tweezers and this method enables to fix a free droplet spatially and to eliminate the effect of the fiber. This paper reports the results of their basic experiments. The n-pentane droplet was successfully suspended by optical tweezers system. The maximum droplet diameter was around 70μm and this is extremely larger than that of results in the previous studies. Vaporization behavior is also observed. In the large droplet suspension by optical tweezers, because the force by optical tweezers balances to the gravity force, microgravity experiments are preferred in terms of droplet suspension.
