Traditionally, volute design for multiblade impeller pumps has been carried out using either the constant-velocity or constant-swirl methodologies. Here, the constant velocity approach was investigated in order to determine whether or not it was appropriate for single-blade-impeller pumps, and whether the theoretical formulation would agree with numerically calculated data. In a numerical approach, three volutes were designed of the constant velocity type with design velocities of 0.8, 1.0, and 1.20 Cref. The performance of all three volutes was calculated using transient, three-dimensional, viscous numerical simulations, using the commercially available ANSYS CFX -11.0 code, over a range of flowrates 0.55 DEWEY : 620.1 ISSN : 0098-2202 En ligne : http://fluidsengineering.asmedigitalcollection.asme.org/issue.aspx?journalid=122 [...] [article] A numerical investigation of the constant-velocity volute design approach as applied to the single blade impeller pump [texte imprimé] / Brian de Souza, Auteur ; Andrew Niven, Auteur ; Richard McEvoy, Auteur . - 2010 . - 07 p. fluids engineering Langues : Anglais (eng) in Transactions of the ASME .
