A new approach to compute multi-reflections of laser beam in a keyhole for heat transfer and fluid flow modelling in laser welding (2013, methodology): “Some variations of this model can be found in the literature [15, 17–21].”
[INVITED] An overview of the state of art in laser welding simulation (2016, background): “These equations are written here with the classical assumptions [13,53,16]), which means a laminar flow with an incompressible and Newtonian fluid.”
A complete model of keyhole and melt pool dynamics to analyze instabilities and collapse during laser welding (2014, methodology): “Cho et al. 5 have used an equivalent 3D model to demonstrate that the Marangoni effect in laser welding conﬁgurations can be neglected.”
Laser Welding Process – A Review of Keyhole Welding Modelling (2015, background): “In Cho and Na (2006), Lee et al. (2002), Zhou and Tsai (2008), Pang et al. (2011), and Cho et al. (2012), the reference cooling temperature is supposed to be the room temperature.”
