| 内容記述 | Detonation is the premixed and self-sustained phenomenon with supersonic propagation speed. If detonation occurs, it may lead to a major accident due to such characteristics. In fact, explosion accidents related to detonation have been recorded [1]. Therefore, it is important to study the detonation characteristics. Ammonia fuel, which does not produce CO2, is one of the most promising fuels for global warming and has become a growing concern around the world in recent years. Ammonia also has the advantages of easy transportation and storage, and industrial production methods have been established. Therefore, the use of ammonia is expected to increase in the future. On the other hand, ammonia is relatively difficult to burn and is known to be a fuel less likely to cause a stable detonation. [2]. Here, attempts have been made to improve the combustion properties of ammonia. For example, there are reports that hydrogen addition has improved the combustion properties of ammonia[3]. On the other hand, there are few examples of detailed evaluation of the propagation mechanism of detonation with ammonia fuel. Two-dimensional analysis of ammonia combution can be used to analyze the formation process of cellular structure and detonation propagation in detail. It is also known that detonation cell structure is an important property of detonation waves. Therefore, it is important to understand the cell structure in order to use ammonia as a detonation fuel in the future. In this study, we attempted to improve the combustion characteristics of ammonia fuel by adding highly reactive hydrogen and evaluated the characteristics of its cell structure. |
