Abstract A numerical model of multiphase flow is developed to investigate the relative contributions of droplet parameters to spray cooling heat transfer. The 2-D model takes into account the effects of surface tension, gravity and viscosity. The heat and mass exchanges of free surface are defined to study vapor bubble behavior in liquid films. The multiphase flow and heat transfer are discussed for the three droplet parameters: initial droplet position, initial droplet temperature, and droplet impact frequency. The heat transfer mechanisms of the three cases are discussed in detail.
