Abstract

We here report on ice droplet collider which uses kinetic energy of the highly accelerated ice droplet for chemical processes by colliding with the target. The method for controlling the ice droplet in gas phase by using microscale phase transition was created. It was confirmed that work given by air pressure directly converts to kinetic energy of the ice droplet. The ice droplet which was accelerated to velocity of 16 m/s at P = 400 kPa of air pressure can get 100 kJ/mol of kinetic energy by using high-pressure system. Chemical reaction can be realized by using this energy for collision.
