    • Computational study of transient flow around Darrieus type cross flow water turbines 

      Lain Beatove, Santiago; Quintero Arboleda, Brian; López Mejía, Omar Darío; Meneses, Diana (American Institute of Physics Inc., 2016-01-13)
      This study presents full transient numerical simulations of a cross-flow vertical-axis marine current turbine (straight-bladed Darrieus type) with particular emphasis on the analysis of hydrodynamic characteristics. Turbine ...
    • Flow regulation at constant head in feedwater pumps in a sugar industry 

      Quispe, Enrique C.; Sousa Santos, Vladimir; S. Quintana, Mario; Gómez Sarduy, Julio Rafael; Viego Felipe, Percy R.; Hernández Herrera, Hernán (Institute of Advanced Engineering and Science, (IJECE), 2019)
      In this paper the feasibility of energy saving by implementing flow regulation at constant load in feedwater pumps in a sugar industry is studied. As regulation strategy, the use of a variable ...
    • Hydraulic and rotor-dynamic interaction for performance evaluation on a francis turbine 

      Lain Beatove, Santiago; Quintero Arboleda, Brian; Garcia Ruiz, Manuel Julian; Orrego, Santiago; Barbosa, Jaime (Springer Verlag France, 2017-08)
      This paper proposes a new methodology to evaluate the technical state of a Francis turbine installed in a hydroelectric plant by coupling computational fluid dynamics (CFD) and rotor-dynamic analysis. CFD simulations ...
    • Numerical study of the effect of winglets on the performance of a straight blade darrieus water turbine 

      Lain Beatove, Santiago; López Mejía, Omar Darío; Taborda Ceballos, Manuel Alejandro (MDPI, 2018-01-28)
      This study deals with the three-dimensional unsteady numerical simulation of the flow around a cross-flow vertical-axis water turbine (CFWT) of the Darrieus type. The influence of turbine design on its hydrodynamic ...
    • RANS and hybrid RANS-LES simulations of an H-Type darrieus vertical axis water turbine 

      Lain Beatove, Santiago; López Mejía, Omar Darío; Quiñones, Jhon J. (MDPI, 2018-09-06)
      Nowadays, the global energy crisis has encouraged the use of alternative sources like the energy available in the water currents of seas and rivers. The vertical axis water turbine (VAWT) is an interesting option to harness ...
    • Simulating and designing small hydrokinetic turbines: A review 

      López Castrillón, Yuri Ulianov; Lain Beatove, Santiago; Ramírez Tovar, Ana María (International Review of Electrical Engineering (IREE), 2018)
      The increased use of renewable energy resources for rural electrification has encouraged research and experimental projects decreasing designs uncertainties. This paper presents a deep and critical review of the design of ...
