Parameter study of TEIS model, two-zone model, and stanitz's equations

Recently TEIS model, two-zone model, and stanitz equations are often used for off-design performance prediction of centrifugal compressor and pump. The prediction results often agree well with experimental data. However these models and equations have some important variables which have a great influence on overall performance prediction curve. But no systematic study about these variables has been performed. So, in this paper, a systematic study about these variables' influence on overall performance prediction curve is performed. Finally the meaning of the variables and the research to be undertaken are discussed
