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 good. 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.
