Short summary
Cold Spray is a novel technology for the application of coatings, in which bonding is realized by the acceleration of powder particles through a carrier gas and their high speed impact over a substrate material. Different nozzle designs are shown experimentally to vary in deposition efficiency, which cannot be explained by standard computational simulations. In order to amend the modelling techniques, a stronger coupling of solid and gas phase is employed, which provided improved results.
