Permeability and Thermal Transport in Compressed Open-Celled Foams

Permeability and Thermal Transport in Compressed Open-Celled Foams

A computational methodology is proposed to describe the fluid transport in compressed opencelled metallic foams. Various unit-cell foam geometries are numerically deformed under uniaxial loads using a finite element method. An algorithm is developed and implemented to deform the fluid domain mesh inside the unit-cell foam based on the deformed solid unit-cell geometry. Direct simulations of the...

New Algorithms for 3-D Imaging and Analysis of Open-Celled Foams

Open-celled foams are three-dimensional networks of polymeric cells. The mechanical properties of a foam depend on the size and geometry of its cells. Since foams have a three-dimensional polyhedral structure, the two-dimensional characterization techniques currently used provide limited accuracy. Nuclear magnetic resonance and x-ray tomography methods offer opportunities for three-dimensional ...
