      The paper refers to the behavior of a radial flow pump vaneless diffuser during a starting period. Results obtained with a 1D numerical model are compared with some new experimental data which have been obtained using 2D/3C ...

      CHERDIEU, Patrick; ccDAZIN, Antoine; DUPONT, Patrick; ccBAYEUL-LAINÉ, Annie-Claude; ROUSSETTE, Olivier; BOIS, Gérard (2013)
      The aim of this article is to present experimental results obtained on a fan composed of a radial impeller matched with a vaned diffuser. There is no volute downstream to the diffuser. Consequently the diffuser outlet is ...

      KHLIFA, Ilyass; FUZIER, Sylvie; HOCEVAR, Marko; VABRE, Alexandre; FEZZAA, Kamel; ccCOUTIER-DELGOSHA, Olivier (2013)
      A promising method to measure velocity fields in complex two-phase flows such us cavitating flows is presented. Dynamics of the liquid phase and the bubbles are both investigated. The measurements are based on ultra fast ...

      ISSA, Abir; BOIS, Gérard; ccBAYEUL-LAINÉ, Annie-Claude (IAHR - The International Association for Hydro-Environment Engineering and Research, 2008)
      Two fundamental types of flow problems besetting water intakes are swirling flow problems in the pump sump and sediment problems at entrance or within intakes. Both problems reduce intake performance and lead to increased ...

      ccCOUTIER-DELGOSHA, Olivier; ccDAZIN, Antoine; CAIGNAERT, Guy; BOIS, Gérard (HPC - Hindawi Publishing Corporation, 2012)
      The cavitating behavior of a four-blade inducer tested in the LML laboratory large test facility is considered in the present paper. Experimental investigations based on unsteady pressure measurements and records from a ...

      PAVESI, Giorgio; CAVAZZINI, Giovanna; CAIGNAERT, Guy; BOIS, Gérard; ARDIZZON, Guido; ccDAZIN, Antoine (EUROTURBO, 2011)
      The paper reports combined experimental and numerical investigations of unforced un- steadiness in a vaneless radial diffuser. Experimental data were obtained within the diffuser using stereoscopic time resolved Particle ...

      ISSA, Abir; BOIS, Gérard; ccBAYEUL-LAINÉ, Annie-Claude (CMFF - Conference on Modelling Fluid Flow, 2009)
      Water for irrigation, domestic and industrial supply as well for some power generation is normally drawn directly from rivers or from reservoir through sumps. The flow at the pump section sump may have large effects on the ...
