摘要: 
This study simulate flow phenomena around windbreak net, probed into the influence on wind reduction by the windbreak net with different densities. To gain additional insight into the density designs of windbreak net, a series of computations with five di

本研究目的以數值模擬防風網之鄰近流場,探討防風網密度對防風功效之影響。經由5組不同密度防風網之數值計算結果,不但證實防風網之遮蔽功效與其配置及密度有關,而且獲致防風網密度之設計準則,可提供工程規劃之重要參考依據;此外,經由3組不同密度防風網之現地與風洞實驗,監測獲得非恆定流之模式與特性,據此對數值方罄應用加以修正進而確認結果。
風場計算係採用微可壓縮配合大渦模擬及有限體積法,以模擬防風網之鄰近紊流流場。經由數值分析結果得知,防風網密度以70%之防風效果最佳,保護距離達14.7H,而密度50%和90%最差
