Computational Analysis of the Effects of Process Parameters on Molten Pool Transport in Cu-Ni Dissimilar Laser Weld Pool

摘要: A three-dimensional, transient numerical model is used for analyzing the effects of process parameters such as laser power and scanning speed on turbulent momentum, heat mass transport in a typical dissimilar metal weld pool copper-nickel binary couple. The conservation equations are solved coupled manner using semi-implicit pressure linked algorithm framework finite-volume approach. Turbulence taken care by employing suitably modified k–ϵ model, which accounts solid–liquid phase change environment. aspects addressed enthalpy-porosity technique. Subsequently, developed to simulate continuous welding couple butt joint configuration different values speed, order assess their influences geometry, cooling rate, heat, momentum species inside t...
