    • 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 ...

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

      Laín Beatove, Santiago; Cruz Vélez, Camilo Hernán; Torres Lozada, Patricia; Escobar Rivera, Juan Carlos; Montoya Pachongo, Carolina (Universidad Nacional de Colombia. Facultad de Ingeniería, 2016)
      En este estudio se evaluó mediante simulación numérica la influencia del cambio en la configuración de entrada de agua sobre el patrón de flujo, condiciones de mezcla y decaimiento del cloro residual libre en un tanque de ...

    • 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)
      En este trabajo se analiza la dinámica del flujo sanguíneo en un modelo realista de la aorta torácica (TA, por sus siglas en inglés) en condiciones transitorias visualizando las distribuciones de velocidad, flujo secundario, ...
