Abstract	Numerical simulations of droplet impact have been performed using a two-phase VOF-based solver. Comparison with experimental data for droplet shape, maximum diameter and minimum height is reasonable. Simulation results for maximum droplet diameter, for a range of conditions pertinent to inkjet printing, have been compared with several empirical correlations; none of the correlations capture all of the results particularly well. Introduction The impact and subsequent spreading of a droplet on a solid surface is encountered in many situations of practical importance, for example, inkjet printing, 3D additive manufacturing and spray coating. The amount of areal coverage provided by a single droplet is an important factor in these industrial settings: it is commonly characterised by the ratio of the maximum dot diameter to the initial droplet diameter, D∗, often called the spreading or splat factor.
