Low Prandtl number convection flows in coarse-grained porous media

Research goal

The aim of the project is to provide a fundamental understanding of, and experimentally validated models for, the influence of coarse grained porous media  on flow, turbulence and heat transfer in liquid steel. These insights and models will make it possible to design and to optimize new strategies for designing blast furnaces and cooling systems, leading to significant energy savings, increased productivity and improved product quality.
