| Summary: | Cell foams (or porous media) have useful applications in industry, such as compact heat exchangers, thus more papersstudy them to explore their potential use in modern technology. An interesting application of porous media is the openvolumetric receiver of solar tower. The objective of this paper is to study the receiver that will be modeled by porousgeometries, ten consecutive grids will be used to characterize the porosity, two types of geometries are conceived, the firstone consists only of square celled grids, the second one is an alternation of square celled grids and triangular celled gridsthat we called hybrid geometry, this geometry is an original work and results in tortuose turbulent flows. The first typegeometry will be used to study high porosities, inlet velocity boundary conditions are from 0.5 to 15 m/s, the turbulent flowis independent of the meshing thanks to the boundary layer mesh type. The obtained results show that the pressure dropdecreases with increasing porosity which is consistent previous studies from the state of the art. |
