Thermohydraulic Aspects in Laser Welding and Cutting Processes
Authors:
Toshiharu Muramatsu, Applied Laser Technology Institute, Japan Atomic Energy Agency; Fukui Japan
Presented at ICALEO 2012
A general-purpose three-dimensional thermohydraulics numerical simulation code SPLICE was developed at JAEA and designed to deal with gas-liquid-solid consolidated incompressible viscous flows with a phase change process in various laser applications, such as welding, piercing, drilling, cutting, etc. The code solves mass, momentum and energy conservation equations simultaneously in a finite difference form to evaluate various complex phenomena, such as a laser light-material interaction, liquid metal t...$28.00
