For this paper, thre-dimensional (3D) numerical simulations have been carried out by means of one 3D model established using FLUENT software according to the indirect dry air cooling towers of one 2x 660-MW power plant. The arrangement types of the flue gas discharge devices include the horizontal and the vertical arrangement types. The flow fields in the cooling towers have been studied. Meanwhile, the thermal and resistance performances have been analyzed. The study results include: (a) When the ambient wind is not considered, the arrangement types have little influence on the thermal and resistance performances of the indirect dry air cooling tower; and (b) when the wind is considered, the horizontal arrangement type plays a role of the cross-wall, which induces a mass flow increase compared with the case without the flue gas discharge devices.
