Development of a coupled CFD—system-code capability (with a modified porous media model) and its applications to simulate current and next generation reactors
… goal is achieved by first implementing improved porous media models in a commercial CFD code and then by judicious coupling of the CFD code with a coarse nuclear system code. Computationally intensive CFD is used in spatial domains where the flow is expected to be three-dimensional; whereas a …

Macroscopic Turbulence Modeling and Simulation for Flow Through Porous Media
Preliminary validation of the model is carried out by simulating a free stream entering the porous medium under consideration. Simulations are carried out for 75% and 95% porosities. Different inlet turbulence intensities are imposed on the free stream to test the model under different macroscopic …

Flow through and around fish farming nets
<p>Computational fluid dynamics (CFD) modeling, tow tank and field measurements were used to investigate current flow through and around net panels and cages. For the numerical computations a porous media model was used to represent the net allowing efficient computation of both exterior and …

Periodic cell models of flow through porous media
Model problems are analyzed to study the microscopic flow within porous media. In Part 1, the primary focus is on the flow near the surface of a porous body. The idealized system consists of two-dimensional media of infinite and semi-infinite periodic lattices of cylindrical inclusions. The …
