“…They found that after four rows of vortex generators the flow reaches a steady periodic regime. A porous structure which is better comparable to our structure is investigated by Horneber et al [18]. By numerical simulations the flow through a row of 8 units of a Kelvin cell is simulated.…”

“…This behavior can be explained by the dominance of the viscous force over the inertial force in Darcy regime [36,48]. Such dissipative viscous mechanism is similar to that observed for laminar flow in the open-cell structures of idealised foams [36] and Kelvin cells [29].…”

“…Therefore, unit cells such as regular pentagonal dodecahedra [27,28], Kelvin cells (the tetrakaidecahedron geometry) [29][30][31], diamond structures [31] and other idealised geometrical cells [32,33] were proposed for pore-scale investigation of the general effects in idealised foam structures based on unit cells, e.g., modelling mass transfer [27], heat transfer [28] and hydrodynamics within foam-based geometries [29][30][31][32][33]. Simulation works based on abstracted foam models are convenient to extract basic characteristics, in the hope of resembling the ones of real foam structures, for designing applications based on foams.…”

“…Boomsma et al (2003) foram os primeiros a apresentar este tipo de modelo geométrico comparando as simulações numéricas com dados experimentais observando uma boa concordância. Anos mais tarde, Horneber et al (2012) usaram essa abordagem para investigar numericamente uma espuma metálica de células abertas. Os resultados mostraram que a rugosidade da superfície influenciou o comportamento do escoamento próximo à parede e também a perda de carga do leito empacotado.…”

“…De acordo com Horneber et al (2012) e Boomsma et al (2003), a simulação numérica 3D de espumas estruturadas de células abertas, mais precisamente a geometria tetradecahédrica (geometria da célula Kevin) é considerada uma boa representação de uma espuma de célula aberta real. É uma forma periódica ideal numericamente optimizada de uma espuma que foi modelada em um programa de CAD, como SolidWorks e posteriormente a malha foi gerada no ANSYS ICEM.…”
