Study of Cooling by Liquid Force Atomization

According to the liquid force atomization mechanism and the form and movement process of droplet, the relationship of droplet minimum diameter and liquid membrane velocity and the required condition of droplet producing are analysed. Using theory modeling and numerical simulates, the relationship of droplet surviving time, movement distance and the droplet diameter are studied. And furthermore, the effect of droplet diameter on atomization cooling is also studied. The results show that the droplet made of liquid force atomization should be dispersal droplet in order to gain better atomization cooling effect.
