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 -
