Abstract
Internal structures of heat exchangers, nuclear reactors, chemical reactors filled with dispersed materials etc. can be considered as a porous structure. Resolving each detail of such structures is technically not feasible. Normally a detailed analysis of the boundary layers is performed and the results are used to compute integral turbulence sources for a large scale analysis. Note the necessary condition that such approach works: The computational volume contains a structure with all its representative parameters but not part of it.
