Optimization of a parameter in laser heating process

Htin Linn Oo



The aim of this work is the parameter modeling of the metal heating process by laser heating. For these simulations COMSOL Multiphysics 5.3a is used. The transient control of the laser beam is modeled by dynamic equations in the code. The used heat transfer module of COMSOL offers two possibilities of modeling the interaction between laser beam and metal. The first one is that the laser beam is regarded as an incoming thermal flow at the metal, at the other way basically the modeling of the laser beam as a local volume heat source is on focus. The results of the modeling, that have been achieved, show a good agreement between model and investigation, being an important part of further research works.
