New FEM - Programs for modeling coupled processes of selective vapor condensation during laser processing of materials

Abstract

This research presents a computer model for conjugate heat and mass transfer during laser processing of materials. The computer programs based on FEM, which allow to predict the processes of formation of evaporation and condensation zones on the surface areas surrounding the crater are implemented. There is the presence of three modes of operation, differing in the configuration of evaporation zones - condensation. The identified control parameters change modes. A phase diagram for the implementation of process modes is proposed. Finally, the research discusses the possibility of managing the process. © 2020 American Institute of Physics Inc..
