Papers by Keyword: Centrifugal Atomisation

Abstract: A complete description of the parts of a centrifugal atomizer, with geometries and dimensions are shown. Tests of atomization were carried out by using pure tin metal in air atmosphere. Mathematical simulation of the thermodynamics of the process was successful to describe the centrifugal atomization, showing a maximum experimental correspondence mismatch of 14%.

Abstract: A model has been developed for the velocity and temperature evolution of a metal alloy droplet with travel distance in centrifugal atomisation. The droplet velocity decreases rapidly with increasing travel distance. The degree of droplet cooling at a certain travel distance decreases with increasing droplet velocity, increasing diameter and decreasing temperature, and is also affected by the droplet physical properties. The solidification of the droplets is largely dependent upon the latent heat removal.
