Modeling › Process Modeling and Simulation: Energy Transport

 

The experimental research is performed in close collaboration with computational modeling, where various constitutive equations for material behavior and/or new phenomena are implemented into research software and models for materials processing are validated against experimental data. This thrust area of energy transport includes efforts for the understanding of novel processes such as infrared radiant processing and photonic processing of semitransparent materials as well as traditional processes, such as laser processing of metallic components.

Understanding the energy transport is very important to the design of materials processing processes. For example, multilayered, semitransparent materials that are exposed to a broad spectrum of radiant energy produce a complex energy distribution and temperature evolution throughout the structures. For short irradiation times of samples made of different materials, the estimation of the optimum combination of process parameters is a difficult task. The process parameters can be obtained efficiently from a combined experimental and computational process analysis. The aim of this thrust area is to develop process models for predicting the energy distribution and corresponding temperature distribution during the processing of various materials that are exposed to various external energy fields.
