| Abstract Scope |
Cold spray (CS) additive manufacturing technology is used for repairing damaged components and fabricating individual parts for aerospace, medical, and other critical applications. In the CS process, high-speed feedstock particles are deposited onto substrates upon impact. Studies show that the distribution of particle velocities and their positions within the jet can influence the properties of the deposition. Particles positioned outside the jet core are likely to have non-orthogonal impact directions, resulting in lower deposition efficiency. High-fidelity numerical analysis is conducted to investigate the effects of flow turbulence and particle pre-processing conditions on their dynamics within the CS system. Large-Eddy Simulation (LES) with a subgrid scale model is used to estimate the small, transient turbulent eddies present in the flow. Numerical observations are validated with measurements from the experimental setup using an in-house developed instrumentation system. The analysis is performed using copper and ferromanganese particles. |
