摘要: 为了提高气体喷射器的设计效率,基于经典的气体动力学函数法并结合国内外优秀的设计模型,对喷射器结构尺寸计算方法进行系统的梳理总结,并利用VB.NET开发出一套气体喷射器设计软件。该软件由输入输出模块、参数计算模块、结构设计模块和性能曲线绘制模块等组成。本软件适用范围较广,不仅能对三种常见压缩比的同相气体喷射器进行设计计算,还考虑了气液及气固两种异相喷射器,大大丰富了软件的使用范围。软件界面简洁,操作方便,采用本软件可以大大缩短设计周期,提高设计效率和计算的准确性。

关键词: 喷射器, 设计计算, VB.NET, 软件设计, 喷射系数

Abstract: In order to improve the design efficiency of ejectors, the calculation method of ejector structure size was systematically investigated, and a software was designed by VB. NET based on the combination of the classic theory of ejectors and the excellent design models of both domestic and foreign countries. The software is mainly composed of four parts of modules, which are the input/output module, the eject coefficient calculation module, the structural design module and the performance curve drawing module. This software has a wide range of application because it can not only resolve the ejector of three different compression ratios, but also deal with the two-phase ejector of gas-liquid and gas-solid operating condition, which greatly enriched the function of the software. The interface of the software is simple and easy to operate, leading to the improvement of the calculation accuracy and the design efficiency of ejector structure.

Key words: ejector, structural design, VB.NET, design software, eject-coefficient
