| Research Abstract |
In this research, a droplet in air is accelerated to more than 10m/s and collided with another droplet by developing new fluidic control methods for focusing the kinetic energy to the collision at the droplet surface and inducing new chemical reactions. The microscale droplet was prepared using Laplace pressure induced by partial hydrophobic surface modification. The droplet was converted to ice phase by partial temperature control. The ice was fixed at the low temperature area and adhered to the wall. The air pressure applied was increased to 400kPa, and the droplet was shot by overcoming the adhering force. As a result, the droplet was accelerated to 20 m/s.
