概要 |
Huadian Group's first wind project in Yunnan, Duogu wind farm, has been approved by the Provincial Development and Reform Commission. The acquired site is in Mengzi, south east of Yunnan Province. The... developer intends to employ 33 units of 1.5MW turbines in this new wind farm (49.5MW) and the total cost of construction has been estimated to be CNY449.7 million ($69.61 million). The present study compared the prediction accuracy of two CFD software packages for simulating a flow around an actual escarpment with a steep slope: 1) OpenFOAM (turbulence model: SST k−ω RANS), which is a free, open source CFD software package developed by OpenCFD Ltd at ESI Group and distributed by the OpenFOAM Foundation and 2) RIAM-COMPACT【○!R】 (turbulence model: the standard Smagorinsky LES), which has been developed by the lead author of the present paper. Relatively good agreement was obtained between the OpenFOAM and the RIAM-COMPACT【○!R】.続きを見る
