The properties of a thermally sprayed coating, such as its durability or thermal conductivity depend on its microstructure, which is in turn directly related to the particle impact process. To simulate this process, we present a 3D smoothed particle hydrodynamics (SPH) model, which represents the molten droplet as an incompressible fluid, while a semi-implicit Enthalpy-Porosity method is applied for modeling the phase change during solidification. In addition, we present an implicit correction… 
Quantitative Evaluation of SPH in TIG Spot Welding
TLDR
It is shown that SPH is able to yield excellent results, especially given the observed deviations between the investigated FEM methods and as such, the accuracy of the method for an industrially relevant engineering application is validated.
