Cavitation consists in a local mass and heat transfer phenomenon, which involves the formation and collapse of vapor cavities. For industrial applications, the interest is focused on Fluid Machinery, increasing the difficulties due to the complex geometrical arrangements and working conditions. Within such frame, the work on cavitation for centrifugal pumps has been a matter of study in the last decades. The main conclusion of the present study is to show the NPSH curves for two available geometries with different impeller diameters and, then, a comparison is done. The results open the test case to possible numerical implementation and future analysis.
