Abstract
An experimental study on the behavior of droplets impinging on a solid flat surface was earned out in the present study. Breakup of a liquid droplet impinging on a solid surface has been investigated experimentally for various liquids With different properties The liquid droplet temperature and incident angle were chosen as major parameters Liquid droplet temperature and incident angle vaned in the range from -20℃ to 30℃ and from 30˚ to 60˚, respectively. it was found that the variation of droplet temperature influences upon the mean diameter and uniformity of droplets which were bounced out from the solid surface With increase of incident angle the dispersion mass fraction increases, causing the decrease of liquid film flow rate As the liquid temperature increases, dispersion mass fraction increases since the surface tension decreases.
