| Abstract Scope |
Cold spray additive manufacturing is employed for both repairing damaged components and producing standalone parts in critical sectors such as aerospace and medicine. In this process, feedstock particles are accelerated to high velocities and deposited onto a substrate upon impact. Research indicates that the velocity distribution and spatial positioning of these particles within the spray jet significantly affect the quality of the resulting deposition. Particles located outside the core of the jet tend to strike the surface at oblique angles, which can reduce deposition efficiency. A new delivery tube configuration with a co-flow attachment is investigated using a high-fidelity large-eddy simulation model. The new configuration shows reduced flow turbulence, which leads to a decrease in particle dispersion.
