  Cold spray technology is a quickly growing manufacturing technology which
impacts lots of industries. Despite many years of studies about the
comprehension of the phenomena and the improvements of the performance of the
system, ensuring high fidelity simulations remains a challenge. We propose in
this work a detailed high fidelity modeling and simulations giving more insight
of the phenomena appearing in cold spray such as turbulence, oblique shocks,
bow shocks, fluctuations, particles motion and particles impacts. It is mainly
based on a richer model known as the Detached Eddy Simulation (DES) model.
Moreover, we present several analysis of various existing models for both
validations and comparisons purposes. Finally, this high fidelity framework
will allow us to deal with a new configuration showing an improved performance
assessed with the previous models.
