WebHeterogeneous porous medium. We may have a porous medium in which the viscous and inertial resistance pressure drops are not the same in different directions due to the anisotropy of the porosity. ANSYS Fluent software gives us the ability to define viscous and inertial resistance separately, in three directions of X, Y, and Z (for two-dimensional … 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.
