| 摘 要： | 以大空间中圆形陶瓷微管形成的液体乙醇扩散火焰为研究对象.用实验和数值解析的方法研究了微尺度液体乙醇扩散火焰的火焰结构和温度分布.实验证明,在喷管尺寸相同条件下液体乙醇流量增大,火焰温度随之升高,火焰体积增大.通过数值解析观察了火焰和微管内温度场分布以及微管内热质传递现象.数值解析结果与实验一致.

| Abstract: | Tructure and temperature distribution of circular ceramic micro-tube liquid ethanol-air diffusion micro-flame in large space were investigated experimentally and numerically.Experiments confirmed that with the same size of the micro-tube liquid ethanol flow rate increasing,both the flame temperature and the flame volume subsequently increased One-step reaction model was used in ethanol-air combustion reactions in the numerical analysis.The calculation results were the same as them in experiments.And tempera... |
