项目摘要
In order to make clear the micro-structure of premixed turbulent flame, many studies have been carried. Because, the micro-structure has large influence on the turbulent mass burning velocity.The head investigator et al. proposed a turbulent combustion zone model which considered the burned fraction ratio of the wrinkled laminar flame zone to the distributed-islands flame zone.Combustion experiments were carried out for premixed turbulent flame propagating in strong and steady turbulence field. The turbulent flame propagates only in one direction of the combustion chamber in this experiment. Schlieren-images of the turbulent flame were photographed from both normal and parallel to the propagating direction. The electrical floating potential of the flamelets was detected by ion probes near the central axis and near the wall. The obtained schlieren-images photographed from flame propagating direction show very complicated fringes and the measured average distance between successive fringes decreases rapidly with increasing the turbulence intensity and slowly with decreasing the laminar flame thickness. The measured average distance between successive fringes in one photograph shows smaller value near the wall than near the central axis. The number of peaks of ion signal near the wall is larger than near the central axis. These results suggest that the micro-structure of turbulent propagating flame is strongly influenced by the wall.More than 70mm of turbulent flame zone thickness was measured by a double ion-probe method for mixtures with small laminar burning velocity at strong turbulence intensity. This value of zone thickness is high enough to analyze the micro-structure of premixed turbulent flame.Since this combustion chamber is accessible from two directions, laser-doppler anemometry and laser-sheet optical method in addition to the schlieren method mentioned above can be easily applied for measurement of turbulent propagating flame.
为了明确预混湍流火焰的微观结构,人们进行了大量的研究。因为,微观结构对湍流物质燃烧速度有很大的影响。提出了考虑褶皱层流火焰区与分布岛火焰区燃烧分数比的湍流燃烧区模型。对预混湍流火焰在强稳态湍流场中传播进行了燃烧实验。在本实验中,湍流火焰仅沿燃烧室的一个方向传播。湍流火焰的纹影图像是从法向和平行于传播方向拍摄的。火焰的浮动电势由中心轴附近和壁附近的离子探针检测到。从火焰传播方向拍摄的纹影图像显示出非常复杂的条纹,并且测量到的连续条纹之间的平均距离随着湍流强度的增加而快速减小,并且随着层流火焰厚度的减小而缓慢减小。一张照片中连续条纹之间测量的平均距离显示,靠近墙壁的值比靠近中心轴的值更小。壁附近的离子信号峰值数量多于中心轴附近的离子信号峰值数量。这些结果表明,湍流传播火焰的微观结构受壁面的影响很大。对于强湍流强度下层流燃烧速度较小的混合物,采用双离子探针法测量了超过70mm的湍流火焰区厚度。该区域厚度值足够高,足以分析预混湍流火焰的微观结构。由于该燃烧室可以从两个方向进入,因此除了上述纹影法之外,激光多普勒风速仪和激光片光学法也可以很容易地应用于湍流传播火焰的测量。
