Abstract

Single-unit and multi-unit models of porous media (metal felts) have been used to investigate thermal fluid-structure interaction phenomena in a liquid sodium system. Micro-scale aspects have been studied via numerical simulations. The permeability of metal felts has been measured experimentally to verify the reliability of the models used. This integrated approach has allowed a proper evaluation of the interdependencies among phenomena on different scales (including relevant information on skeleton deformation and pressure drop as a function of different parameters). Pressure drop generally increases with velocity and heat flux for both laminar and turbulent flows. The final deformation is greater when turbulence is considered. When the flow is laminar and its rate changes linearly with time, the deformation amount also varies linearly.

Keywords

metal felts, liquid sodium, fluid-structure coupled, pressure drop, deformation, permeability.
