Advanced simulation of liquid melt flows in controlled continuous casting
Steel production is an energy intensive process. Continuous casting of steel (metals in general) aims at high production speed at as low as possible energy usage. Stability of the flow in the casting process plays a vital role in product quality and process performance. Electromagnetic actuators can be used to control and stabilize the multiphase metal flow. Computational Fluid Dynamics (CFD) can play a vital role in understanding the interplay between fluid dynamics and electromagnetic forces. Moreover, it allows studying different actuator strategies. The work also involves fundamental scientific analyses and engineering design with groups at Helmholtz-Zentrum Dresden-Rossendorf, at the universities of Liberec and Bath and at different industry partners.
Research Activities / Objectives:
- Development of a robust numerical model for two-phase liquid metal flows under the presence of actuating electromagnetic fields
- Extensive model validation with experimental data from LIMMCAST (HZDR)
- Predictive simulation of different electromagnetic actuator designs
- Numerical support to actuator design and control
- Reduction of model complexity via dedicated new sub-models for e. g. bubbly flows
