WebFeb 14, 2024 · The picture above is the part of 7.2.3.8.7. It says that Fluent assume porous the 100% open media, in other word, no solid part in simulation world, and people who define the pressure drop through porous media must use superficial velocity to determine either permeability or inertial coefficient. WebThe computational fluid dynamics platform Fluent is used to perform melting process in the enclosure. It uses enthalpy-porosity approach for modeling melting process [60,61]. In this method, instead of tracking the melt interface front, it calculates melt fraction (liquid fraction) in the computational domain.
