Abstract : numerical simulation by cfd was carried out to understand the hot current behavior in a tunnel with longitudinal ventilation . it becomes clear that fire source modeling is very important because the hot current behavior is strongly affected by the fire source position and is sensitive to methods in the modeling of the fire source . the flame area which has developed from the fire source is an area of chemical reaction caused by combustion . even if grids in the vicinity of the fire source are made fine , it was difficult to simulate the heat generation area with consideration to this chemical reaction through using a method for setting the heat release rate simply on the fire source surface . therefore , we proposed a method adopting the knowledge on flame shape under the longitudinal ventilation and incorporating it into numerical simulation and it showed a good agreement with the experimental results . it was shown through experiments in a tunnel with longitudinal ventilation that the hot current developed toward the tunnel center downwind from the fire source near a wall . the cause was investigated by numerical simulation and it became clear from the results that the spiral air by the fire plume created a vortex in the crevice between the wall and the plume 文摘:運用cfd進行數字模擬,以了解縱向通風隧道內熱煙氣流的特性.通過模擬發現對火源進行模擬非常重要,熱煙氣流特性受火源位置的影響很大,并且對火源模擬方法很敏感.火源生成的火焰區是燃燒引起的化學反應區域.即使火源附近的木垛排列完好,也很難在考慮這些化學反應條件下模擬熱生成區域.建議考慮縱向通風隧道內火焰形狀并對它進行數字模擬.模擬結果與試驗結果非常吻合.試驗證明,在縱向通風隧道內,熱煙氣流從靠近墻體火源處順風向隧道中心蔓延.數字模擬結果發現,火災羽流造成的螺旋上升空氣會在墻體和羽流之間形成一個渦流區

Southerly gales brought severe windshear and turbulence to the airport . as southerly gales blew across the northeast - southwest oriented hilly ranges over lantau , streaks of low wind flow emanated from the hills while streaks of high wind flow appeared downwind of the gaps 當晚主要吹南風，強度達烈風程度，為機場帶來強烈風切變和湍流。當這些烈風程度的南風吹越大嶼山上東北走向西南的山脈時，在山脈及山谷的下游分別形成條紋狀的弱氣流及強氣流。
If it takes six hours for people in the vicinity to evacuate , then calculations show that nearly everyone downwind of the blast within approximately five kilometers would still be killed by fallout , and half the inhabitants eight kilometers away would die 如果附近的民眾需要六小時疏散，計算顯示，爆炸點的下風處大約5公里內，所有人都會死于輻射性落塵， 8公里內的居民也有一半會死亡。
Some of the above facilities have special locational requirements , for example , facilities with gas emissions should be located in a downwind location such that the impact of the emissions on the population could be minimised 以上部分設施，要求特殊的興建選址，例如會釋放氣體的設施應建于逆風的地點，以盡量減低釋放氣體對人口造成的影響。

As the northeastern part of hong kong , including yuen long and tung chung , is to the downwind side of prd , it is more susceptible to the influence of regional air pollution than other areas 由于本港西北部地區如元朗及東涌較直接在珠江三角洲下風，因此受區域性空氣污染的影響較其他地區為大。
