The collision dynamics is primarily affected by the droplet weber number we and the film thickness scaled by the droplet radius h that while droplet absorption by the film is facilitated with increasing droplet weber number the boundary of transition is. The collision dynamics including evolution of the surface contours of the droplet and film as well as the energy budgets were then simulated by using a front tracking technique. Abstract three physical phenomena were experimentally and computationally investigated in this research namely the dynamics of head on droplet droplet collision head on droplet film collision and laminar premixed flames with emphasis on the transition between bouncing and merging of the liquid surfaces for the droplet collision studies and on the susceptibility to exhibit hydrodynamic .
