Hydrodynamic characterisation of a garman-type hydrokinetic turbine
(MDPI, 2021-05)This paper presents a numerical study of the effects of the inclination angle of the turbine rotation axis with respect to the main flow direction on the performance of a prototype hydrokinetic turbine of the Garman type. ... -
Influencia del tipo de alabe en el desempeño hidrodinámico de una turbina tipo Darrieus
(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
(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 ... -
A review on computational fluid dynamics modelling in human thoracic aorta
(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
(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, ... -
Synergy effect modelling of cavitation and hard particle erosion: implementation and validation
(Elsevier B.V., 2021)The prediction of the wear behaviour of components under conditions of cavitation and hard particle erosion requires the implementation of a new model capable of accounting for the accelerated damage due to the synergic ...
