基于Java Web的CEA程序移植

Java Web-based CEA program’s porting

摘要:

CEA（Chemical Equilibrium with Applications）是NASA Lewis研究中心基于最小化自由能方法研发的计算化学平衡程序，主要应用于液体火箭发动机化学热力平衡过程（燃烧）分析。在将近50年NASA研究人员的不断更新中CEA得到了完善，其中除了通用的化学平衡计算方法，还包括了诸多计算方法，这些方法广泛应用于空气动力学和热力学的研究当中。但是因为程序的高度定制化，并没有得到更加普遍的使用。对CEA程序的结构和工作流程进行了研究，提出一种基于Java Web的移植方法，实现了程序的Web完整移植，并且将算法封装为URL API供开发人员调用。一方面增加了程序的便携性，另一方面API的封装降低了二次开发难度，具有实际的应用价值。

Abstract:

CEA (Chemical Balance and Applications) is a computational chemistry balance developed by NASA Lewis Research Center based on the minimization of free energy methods. It is mainly used in the chemistry thermodynamic equilibrium process (combustion) analysis of liquid rocket engines. CEA has been refined over nearly 50 years of constant renewal by NASA researchers, in addition to the common chemical equilibrium calculation methods, and many computational methods, which are widely used in aerodynamic and thermodynamic studies However, because of the software deeply customized, and did not get more common use. This article introduces the structure and workflow of the CEA software, proposes a Java Web-based migration method, implements a complete migration of the Web software, and encapsulates the algorithm as a URL API for developers to invoke. On the one hand, it increases the portability of the software; on the other hand, the encapsulation of the API reduces the difficulty of secondary development and has practical application value.
