Numerical Study on Powder Stream Characteristics of Coaxial Laser Metal Deposition Nozzle
A 3D model was established to accurately simulate the internal and external powder stream characteristics of the coaxial discrete three-beam nozzle for laser metal deposition. A <i>k-ε</i> turbulence model was applied in the gas flow phase, and powder flow was coupled to the gas flow by...
