中文摘要:设计了氢气定容燃烧模拟实验装置,利用纹影法在此装置中进行了无隔板和带隔板条件下的氢气空气预混合物燃烧特性研究。结果表明,该装置可模拟氢气、空气预混合物的自燃。本文实验条件下,无隔板实验中,球形火焰两端出现两股火焰;氢气空气预混合物的自燃首先发生在球形火焰前锋与两侧壁面的夹角区域。带隔板实验中,2种方案都可实现自燃;其中第2种方案可有效阻断火焰从上燃烧室传播到下燃烧室,进而实现自燃。

Abstract:A hydrogen fueled constant volume combustion simulation apparatus was designed. By means of Schlieren method, combustion characteristics of hydrogen-air pre-mixture were studied in the apparatus on the condition of no adaptor and built-in one. The result showed that it was able to simulate the auto-ignition of the pre-mixture. Under the experimental conditions, there was a jet of flames on both sides of the spherical flame respectively in the test with no adaptor; the auto-ignition of unburned gas appeared firstly in the angle between the spherical flame front and the chamber wall. In the test with built-in adaptor, it could achieve auto-ignition through both plans. The second plan can effectively prevent the flame propagation from the upper chamber to the lower one, and the unburned gas was auto-ignited.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
