Efficient three-dimensional FEM based algorithm for the solution of convection in partly porous domains

摘要: Abstract In this paper, the authors present an efficient three-dimensional algorithm, based on fully explicit matrix inversion free finite element version of Characteristic Based Split (CBS) scheme, and apply it for first time to simulation complex thermo-fluid-dynamic problems in domains containing simultaneously a fluid porous layer. The stability analysis recently developed two-dimensional algorithm is here extended version. Unstructured grids have been successfully employed solve interface problems. code produces effective solution 3D problems, does not require large computing resources. advantages deriving from algorithm’s stability, use unstructured meshes low requirements make procedure powerful flexible tool modeling real life used both forced natural convection partially domains.
