    • Computational fluid dynamics modelling and simulation of an inclined horizontal axis hydrokinetic turbine 

      Lain Beatove, Santiago; López Mejía, Omar Darío; Contreras Montoya, Leidy Tatiana (MDPI, 2018-11-14)
      In this contribution, unsteady three-dimensional numerical simulations of the water flow through a horizontal axis hydrokinetic turbine (HAHT) of the Garman type are performed. This study was conducted in order to estimate ...

    • 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 ...

    • Effects of water inlet configuration in a service reservoir applying CFD modelling 

      Laín Beatove, Santiago; Cruz Vélez, Camilo Hernan; Torres Lozada, Patricia; Escobar Rivera, Juan Carlos; Montoya Pachongo, Carolina (Universidad Nacional de Colombia. Facultad de Ingeniería, 2016)
      This study investigated the state of a service reservoir of a drinking water distribution network. Numerical simulation was applied to establish its flow pattern, mixing conditions, and free residual chlorine decay. The ...

    • Influencia del tipo de alabe en el desempeño hidrodinámico de una turbina tipo Darrieus 

      Santiago Beatove, Laín; Meneses, Diana; López, Omar (Revista Visión Electrónica, 2013-07)
      The study of vertical axis turbines has gained great interest in recent years for its great potential. Computational fluid dynamics (CFD) is an alternative analysis tool that is being used for the understanding of the ...

    • Numerical simulations of active flow control with synthetic jets in a Darrieus turbine 

      Lain Beatove, Santiago; López Mejía, Omar Darío; Velasco, D. (Elsevier, 2017-12)
      This study presents two-dimensional numerical simulations of the flow around a cross-flow vertical-axis water turbine (straight-bladed Darrieus type) using active flow control by means of synthetic jets. The performance ...

    • 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 ...

    • A review on computational fluid dynamics modelling in human thoracic aorta 

      Laín Beatove, Santiago; Caballero Gaviria, Andrés David (Universidad Autónoma de Occidente, 2013-06)
      It has long been recognized that the forces and stresses produced by the blood flow on the walls of the cardiovascular system are central to the development of different cardiovascular diseases. ...

    • Simulation of unsteady blood flow dynamics in the thoracic aorta 

      Laín Beatove, Santiago; Caballero Gaviria, Andrés David (Universidad Nacional de Colombia. Facultad de Ingeniería, 2017)
      In this work, blood flow dynamics was analyzed in a realistic thoracic aorta (TA) model under unsteady-state conditions via velocity contours, secondary flow, pressure and wall shear stress (WSS) distributions. Our results ...
