Spray wall impingement results in liquid film deposition on walls, especially when the surface temperature is below the liquid saturation temperature. Once formed, the liquid film may exhibit a secondary breakup due to the impact of the succeeding droplets of the spray. In this study, a thin liquid film was deposited on a surface which was heated to near the saturation temperature of the liquid at ambient pressure. The film was impinged by parcels of uniform-size droplets which included one or two droplets. The results show that the liquid film stability is a function of the number of impinging droplets in a parcel, the relative arrival time of the impinging droplets, the droplet Weber number, and the liquid film thickness. Impinging parcels of two droplets at We = 200 on a liquid film at different film thicknesses resulted in three different modes of film breakup; each mode was associated with a different liquid film thickness range. When the liquid film thickness was about the same as the droplet diameter, parcel impingement resulted in a maximum probability of film atomization.
