火焰形狀
英文
flame profile-

在石柱的外面可以看見火焰形狀的太陽石，也可以看見在石柱和太陽石之間的犧牲石。Meanwhile in the condition of high temperature, water vapors can participate in combustion. water gas reaction will happen, which will reduce carbon particle in flame, and reform combustion performance, so improve combustion efficiency. the article developed a kind of technology of water injection into intake ports for 4135g diesel engine, meanwhile designed a suit of water injection system
同時在高溫條件下，水蒸汽參與燃燒，部分水分子與未完全燃燒的熾熱的炭粒發生水煤氣反應，形成可燃性氣體，從而減少了火焰中的炭粒，提高了油的燃燒程度，改善了燃燒狀況，提高了油的燃燒效率。In order to meet the needs of controlling the flame shape, a four - channel coal burner is available
為了滿足控制火焰形狀的需要，可以採用四通道噴煤管。Above this is a large blue bodhicitta, and the shape is like that of a drip or a candle flame
在此之上，有一個大的藍色菩提心，其形狀是像水滴或蠟燭的火焰。Through simulated results, we can receive ideal flamethrower shape, root air, and the obliquity of spin vane so that plateau oil - fired warm air heater ignition easily, flame is stabilization and burn sufficiency
從而得出使高原燃油暖風機易點火、火焰穩定、燃燒充分的噴火筒形狀、根部風的大小以及旋流葉片的傾斜角度，為工程技術人員設計高原燃油暖風機提供一定的根據。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
