Abstract

Porous medium theory is introduced to simplify the muffler array installed in air- cooling platform in this paper. According to the definition of porous medium, the discussion and analysis on geometric structure and flow field characteristics of muffler array show that, the using of porous medium equivalent model for the muffler array is reasonable. The characteristic parameters of porous medium equivalent model are obtained by the measurement and simulation methods. Furthermore, the whole simulation model of air-cooling platform is built with the porous medium equivalent model of muffler array. Then, the effect of muffler array structure on the performance of air-cooling platform is studied with the flow field numerical simulation. The results show that, for the case without environment wind, the air flow of air-cooling platform with muffler array is well distributed, except for the less of air flow; for the case with environmental wind, the installing of muffler array effectively improve the orderliness of the intake air, which is benefit for fans’ working. Meanwhile, the increasing of the intake air distance of air-cooling platform caused by the muffler array is benefit for controlling the reflux of hot air. The numerical simulation analysis on flow field of air cooling platform with muffler array can provide assistance for the design and improvement of muffler array to reduce the air-cooling platform’s noise.
