This paper presents a study of the gas-jet wiping process, which is used in coating techniques to control the final coating thickness applied on a substrate. Numerical simulations are performed using the FLUENT commercial software, with the Volume of Fluid (VOF) model coupled with Large Eddy Simulation (LES). The comparison with results from an analytical model, (with and without surface tension), and from dedicated experiments shows good agreement. The realizable k-ϵ turbulence model is used to reduce the computation time, but with no satisfactory agreement compared with LES and experiments.
