| 中文摘要 | 该文分析了数据库技术应用于循环流化床(CFB)研究工作的必要性与可行性介绍了Oracle数据库管理系统在CFB实验数据库的建立和管理工作中发挥的作用,探索了CFB数据库为CFB研究工作提供服务的途径和方法.CFB实验装置的重建对数据库提出了新的要求,为此,对数据库进行了升级和修改.在此过程中运用了多种数据库工具软件.经过升级和修改的数据库能够更好地完成实验数据存储和分析的工作.用户能够通过两种途径查询数据库中的数据,分别是数据库应用程序和数据库网站.该文介绍了使用VB6.0开发数据库应用程序的技术细节,讨论了访问数据对象的不同方法.介绍多种数据库网上发布的技术,比较了各种技术的优势和不足.使用ASP技术实现了CFB数据库的网上发布. |
| 英文摘要 | The possibility and methodology of the application of database technology in Circulating Fluidized Bed (CFB) research is concerned in this work. An Oracle database management system is used to store and analyze the experimental data from a set of well-instrumented CFB equipment. A database application program and a website are available while visit the database. Two sample methods to use the data in the CFB database to serve the research were discussed. CFB have found wide application in the chemical process industries due to their superior gas-solid contacting ability. However the fluid dynamic behavior of these systems is still not fully understood because of the nonlinearity, complexity and asymmetry of CFB flow. For this reason, experiments performed in industrial and semi-industrial equipment, in which wall effects are not predominant, are very important. The rebuilt CFB equipment needs a new database system to match the changes on it. The CFB database was upgraded and reshaped. The new database can work well with the new equipment. Users can visit the database through two different channels. One is by the database application program; the other is by the database website. Two different ideas to use the database data on CFB research were practiced. One is to validate the mathematical model of CFB solid-gas two-phase flow by the database data. The software package based on Energy-Minimization Multi-Scale model was validated. The other is to describe the dynamical behavior of the solid-gas two-phase flow in CFB equipment by the Modified Particle Froude Number with the assistant of the experimental data in the CFB database. |
