Study of heat transfer in models of FCC, BCC, SC and DEM porous structures with different porosities

Abstract In the present work, we investigated effect of geometry open cell foam material on value pressure drop and heat flux. We create models porous media with an ordered (FCC, BCC, SC) disordered (DEM) structure different values porosity: 0.7; 0.75; 0.8. Numerical modeling was carried out in ANSYS Fluent software (v. 19.0) for various air flow velocities. At porosities 0.7 0.75 there is a noticeable increase BCC FCC packings, respectively. This due to features creating these packings. porosity 0.8, largest corresponds packing cells. The structures show approximately same flux at velocities 0.01 0.05 m/s. 0.25-1.25 m/s, packing. above correspond lowest SC packaging are observed all porosities. Also, has and, therefore, highest energy efficiency values.
