Two-dimensional heat transfer and melt flow in the laser-impact zone at selective laser melting of thin walls -- II: Modeling

Autor: Gusarov, Andrey V., Tarasova, Tatiana V., Grigoriev, Sergey N.

Part II of the present work concerns modeling and analyzing the experimental data obtained in Part I. A computational fluid dynamics (CFD) model of two-dimensional conductive heat transfer and thermocapillary-driven convection is developed. The conse
