Outline of Final Research Achievements

Hybrid levitation system is constructed with a counter-faced ultrasonic phased array and an opposed cylindrical electrostatic electrode. We developed a prototype device to confirm the feasibility of a hybrid levitation system with electrostatic and ultrasonic. After that, we confirmed droplet levitation characteristic of each system. In addition, For the realization of the non-container process technology, we elucidated a correlation between flow structure and evaporation behavior using Mach-Zehnder interferometer, stereo PIV method and so and then we realized transportation, coalescence and mixing by non-contact manipulation of levitated droplets. This technology is a result that leads to creative new thermal fluid process technology.
