| Abstract | In this work the incompressible steady-state flow through a metallic foam matrix is solved by a finite element method. A multiscale approach combining the solution at the pore level by an immersed boundary method and the macro-scale solution with simulated permeability is used. The micro scale solution of the flow takes into account the details characterizing the geometry of the foam (µCT scans) and is used to determine the permeability coefficients in the Forchheimer's model. In a second step, a numerical approach is used to solve the flow at the macro scale by modelling the presence of the foam via a source term corresponding to the pressure drop computed at the micro scale. Such simulation gives the opportunity to solve the flow in complex configurations in which the foam is only a part of the computational domain. The computed pressure drop as a function of the flow rate on the macro scale configuration replicating an experimental set-up is compared with the experimental data for various foam thicknesses. |
