The fin-tube bundles are modeled using porous regions, and fan blade passages are modeled in details to gain accurately fan exhaust flows. Results of numerical investigation indicate that rotational fan exhaust flows lead to inside rotational symmetry flows and distributions of outflows from fin-tube bundles in Aframe ACC cell. When rotational flows are in same direction of ACC outflows in the area, high pressure increases the ACC mass outflows. In the under corner near the ACC inlet with inconsistent interfaces, less ACC outflows appear because of air flows paralleling to the ACC outflow side, influenced by the rotational flows.6 pagesPDFenUniversity of PretoriaHeat transferHEFATFluid mechanicsThermodynamics8th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics 2011Numerical investigationFlow fieldsAir-cooled condenser cellFan blade passagesPower plantFin-tube bundlesPresentation
