Abstract

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
