  abstract  = {The impeller and the casing are the key components of
a centrifugal pump. Although there have been many studies on the
impeller and the volute casing of centrifugal pump, further study of the
volute casing to improve the performance of centrifugal pumps is
needed. In this paper, the effect of cross-sectional area on the
performance of volute casing was investigated using a commercial
CFD code. The performance characteristics, not only at the off-design
point but also for a full type model are required these days. So we
conducted numerical analysis for all operating points by using
complete geometry through transient analysis. Transient analysis on
the complete geometry of a real product has the advantage of
simulating realistic flow. The results of this study show the variation of
a performance curve by modifying the above-mentioned design
