Computational Fluid Dynamic (CFD) Simulations of Liquid Steel Infiltration in Ceramic Foam Structures. Part II: Application to Laboratory-Scale Experiments

The infiltration of liquid TRIP steel into a porous zirconium dioxide foam ceramics is a possible production line for a new composite material. This composite is currently under investigation and development in the Collaborative Research Center 799. Coupled numerical simulations of the hot infiltration process at the pore scale are presented in the paper. The results of the simulations are analysed in order to study similarities and differences between heat and fluid flow phenomena during the infiltration of the foam ceramics. Among others, temperature distributions in the liquid steel and the ceramics are evaluated for typical casting conditions in a laboratory-scale experiment.
