Digital tool: Heat treatment of titanium components
Comparison simulation experiment: temperature curves and cooling rates
Animation of the cooling process
Background:
When titanium components cool down during heat treatment, strong deformations occur due to creep processes.
Objectives:
A simulation tool is to be developed that can predict the temperature distribution in the component in an automated process. The determined transient temperature fields are to be used for a creep analysis with an external FE solver.
Challenges:
Complex transient heat transport process with a variety of transport mechanisms (natural convection, radiation, heat conduction and energy release through structural transformation) on long time scales.
Solution approach:
- Implementation of the model based on pure OpenFOAM functionality with snappyHexMesh as meshing tool and customised transient conjugated heat transport solver (chtMultiRegionFoam)
- Intensive validation and model optimisation on various components based on temperature curves
- Automation of the setup
Application:
Use as a prediction and optimisation tool for heat treatment processes
