| Popis: | 91 The subject of the study is the 3-dimention structure of un-like jet impingement diffusion flame. In the structure of impingement flame, a un-combustibility nitrogen fuel pipe replaces another methane one. By different conditions of mass momentum, we observe the flame structure. Un-like impingement flame supplies a transparent flame structure to analysis the depth of penetrating and the burning stability. In the impingement angle condition of 72.5 degree, fuel velocity and momentum influence the streamline and the stability of flame. The goal of this study is to find the effects of Re and the best momentum ratio. Un-combustibility nitrogen provides an obviously mixing relation. From XY diagrams and Schieren optics observation, in the five momentum conditions, while the methane-nitrogen momentum is 1：1, the average temperature, high-temperature region, and stability are the better than other conditions. By controlling the mass momentum, the centralizing high-temperature region is stable and helpful to control the flame temperature and height. Keywords：impingement diffusion flame, un-like fuel |
