An improved heat transfer and fluid flow model of wire-arc additive manufacturing
International Journal of Heat and Mass Transfer（2021）
Abstract
•We develop & test a mechanistic model of multi-track wire arc additive manufacturing•3D transient model considers mass addition, heat transfer, fluid flow & free surface•Computational speed is significantly enhanced by using an adaptive meshing•Arc pressure and fluid flow are dominant factors in determining deposit geometry•Important model predictions for H13 steel and Ti-6Al-4V are validated with data
