Digital Generation And Radiation In Spherical-Void-Phase Porous Media, Nolan J. Dyck

Electronic Thesis and Dissertation Repository

This thesis documents a novel method for method to generate digital samples of spherical void phase foams to predict effective hydraulic, thermal and radiative properties with the intention of assessing the viability of carbon foam as a volumetric solar receiver. The method employs discrete element modeling software to simulate the compression of spherical bubbles into a fully periodic, cubic domain. These domains were subsequently used to determine a variety of effective transport properties to be used in porous media design problems. The predicted properties agreed well with those obtained through experimental and other numerical methods, notably predicting more accurate properties …
