It is reported that in the recent catastrophic blaze that broke out in garley building, the neon signs and signboards erected on the external walls of the building and the vehicles parked nearby have caused obstruction to both rescue and fire - fighting operations
據報道，在嘉利大發生的災難性大火中，該大外墻的霓虹燈廣告牌和招牌，以及鄰近停泊的車輛，均對救人和滅火行動造成障礙。Based on the relationship between forest fire and weather conditions, many kinds of forest fire danger weather indexes are developed to estimate and predict the possibility of ignition, fire intensity and spread, as well as the difficulty of wildfires control
為實現對林區起火可能性大小、火災強度、火災蔓延速度以及火災撲救難易程度進行評估和預測，國內外專家學者利用森林火災與氣象條件之間的關系研製了諸多森林火險氣象指數的構建方法。The venting reminded scientists of the volcano ' s activity 20 years ago, when it built the dome following its catastrophic 1980 eruption
這次噴射使科學家想起了聖海倫斯火山20年前的那次大爆發，自1980年那場災難性的火山爆發后，聖海倫斯火山口形成了現在的圓頂狀。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
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，並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並對它進行數字模擬.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
