摘要(Abstract)：
工业设计中,一般采用查图表和经验估算的方法进行蒸汽喷射器的设计,过程繁锁,且误差较大,设计出来的喷射器往往不能达到要求的工作性能。本文在研究蒸汽喷射器理论的基础上,依据气体动力学函数法进行计算,并开发了蒸汽喷射器设计软件,结果表明:采用蒸汽喷射器设计软件不仅提高了蒸汽喷射器设计的准确性,而且提高了设计效率。
In industry designing,to refer to the diagram or to estimate empirically is in common use for designing steam ejector,and so the relative lamer error is inevitable and the ejector using foregoing methods sometimes cannot meet the required working performance.In the present dissertation,the author develops a set of software for designing the steam ejector,based on the theory of steam ejector and object oriented programming consideration.The software can not only enhance the accuracy but also increase the designing efficiency.
