Numerical Analysis of the Effects of the Structure Shape and Orientation of Kelvin Cell Porous Structures during Air Forced Convection

In recent years, in order to counteract the growth of environmental pollution and contemporary scarcity various energy sources, researchers have proposed innovative efficient solutions for heat transfer applications. Extended surfaces, which can involve use fins, open cell metal foams, etc., been demonstrated be promising solutions. Open foams consist structs intersecting at nodes resulting stochastic oriented cells. Periodic also attracted great interest. These structures are made a single unit periodically replicated. Kelvin cells Weaire–Phelan ones two conventional elementary this paper, numerical model is developed validated, aiming analysing thermal hydraulic behaviors modified cell-based during air forced convection. Constant porosity (0.9) pore density (40 PPI) were adopted. Five different geometrical configurations (one cylindrical four elliptical) orientations (0–15–30–45°) struts with respect main flow direction investigated. The inlet velocities varied between 0.5 4 m s?1. Interesting results obtained discussed terms pressure drops, coefficients, pumping power per area density.
