Numerical Study of Slip Factor in Centrifugal Pumps and Study Factors Affecting its Performance

摘要

Slip phenomenon is very important factor by it we can know the actual amount of energy transferred to fluid. In this study i test the different parameters which may affect on this phenomenon such as discharge, exit flow angle, number of blades, type of fluid. i found the old Busemann, Stodola, Stanitz, Wiesner, Eck and SRE is correct in some cases only because these relations don't study all factors affected on slip factor. Also the trend of the slip factor in new study such as in X. Qiu there are case which upward trend and others downward trend thus I focus on this phenomenon in this paper.
