AbstractA 3D numerical model is presented to simulate the gas flow and particle movement behavior in the downstream radial injection cold spray nozzle. The particle velocities at the nozzle exit were measured using an optical diagnostic method. The comparison shows that the numerical results of the proposed model can fit reasonably well with the experimental results. The influence of processing parameters (inlet gas pressure and inlet gas temperature) as well as the particle size is discussed. A comparison between the upstream powder loading cold spray system and downstream powder loading system is also made in this study. The proposed numerical model can be considered as a useful tool for the nozzle design and system optimization.
