• An experimental and numerical study of a three-lobe pump for pumped hydro storage applications 

      Gans, Luiz H.A.; Trivedi, Chirag; Iliev, Igor; Storli, Pål-Tore Selbo (Peer reviewed; Journal article, 2023)
      Pumped hydro storage (PHS) plays an important role as a matured technology that accounts for the vast majority of global energy storage capacity, and its expansion is therefore desirable. The expansion of PHS in mid- and ...
    • High flexibility in Francis turbine operation and design philosophy: A review 

      Kverno, Johannes Opedal; Iliev, Igor; Dahlhaug, Ole Gunnar (Peer reviewed; Journal article, 2022)
      This paper examines and discusses how various operation schemes and design philosophies can prolong the expected lifetime of a hydro turbine subjected to many start-stop cycles and high ramping rates. With the proliferation ...
    • Multidisciplinary optimization of a Francis turbine runner 

      Tengs, Erik Os; Charrassier, Flora; Jordal, Maria; Iliev, Igor (Peer reviewed; Journal article, 2022)
      A fully automated multi-disciplinary design optimization procedure for a Francis turbine runner has been developed in a previous task of the Horizon2020-HydroFlex project. The design optimization was limited to blade design, ...
