摘要
基于压气机性能方程推导出一种新的压气机级的数学模型,并在这一模型基础上用Modelica语言和Dymola编译器建立了计算机仿真模型,编成了压气机系统仿真程序。还描述了压气机仿真程序建模系统和面向对象的体系结构,介绍了压气机系统特性分析的应用例子,并进行了仿真验证。结果表明,采用建立的仿真模型能够用来模拟压气机性能。
A new mathematical model for compressor stage modeling and simulation is deduced based on the compressor stage equations in this paper. According to this mathematical model, a computer simulation model has been built using the multidisciplinary object-oriented modeling language Modelica and compiler Dymola. Compressor system simulation program has been developed. In this paper, the compressor system simulation program modeling system and object-oriented architecture are described. Examples of application for compressor system performance analysis are presented. The method is validated by the simulation results of the performance of compressor examples. It is shown that mathematical model will properly simulate the compressor performance.
