Discrete Phase Modeling of the Powder Flow Dynamics and the Catchment Efficiency in Laser Directed Energy Deposition With Inclined Coaxial Nozzles

Sachin Alya, Ramesh Singh
Journal: Journal of Manufacturing Science and Engineering
Article Type: Research Papers
J. Manuf. Sci. Eng. August 2021, 143(8): 081004.
Paper No: MANU-20-1471
DOI: https://doi.org/10.1115/1.4049966
Published Online: March 26, 2021
.... A discrete phase model has been developed to understand the powder flow dynamics at different inclinations and process conditions. The mass flow distribution asymmetries on the focal plane at various nozzle inclinations have been analyzed via the model. The model can predict PCEs at different nozzle...
