Flows in coarse-grained porous media
Research goal
The overall aim of this research project is to provide a fundamental understanding of natural and mixed convection flows in coarse-grained porous media and to provide detailed experimental data to validate and improve developed simulation models. To achieve this aim we will conduct PIV (Particle Image Velocimetry), LCT (Liquid Crystal Thermography) and heat transfer measurements in natural and mixed convection flows in porous media composed of packed beds of spheres. We will also perform X-ray particle tracking in a liquid metal to gain a better understanding of low-Prandtl number thermal convection flow in porous media.
