impeller rim

sciences naturelles et appliquées - iate.europa.eu

▷

Fluid–structure coupling analysis of deformation and stress in impeller of an axial-flow pump with two-way passage... The results show that the values of deformation and stress significantly decrease with an increasing flow rate and a decreasing head, and the maximum total deformation can be found in the impeller rim, while the maximum equivalent stress can be obtained near the impeller hub....
