Effect of extrusion screw speed and plasticizer proportions on the rheological, thermal, mechanical, morphological and superficial properties of PLA
(Multidisciplinary Digital Publishing Institute. MDPI, 2020-09-16)
One of the critical processing parameters—the speed of the extrusion process for plasticized poly (lactic acid) (PLA)—was investigated in the presence of acetyl tributyl citrate (ATBC) as plasticizer. The mixtures were ...
Computational study of transient flow around Darrieus type cross flow water turbines
(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
(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 ...
Surface damage caused by the interaction of particles and a spark-generated bubble near a solid wall
(Elsevier, 2019-11-15)
Machine components operating in a fluid under conditions of cavitation and hard particle erosion can be severely affected by wear, which may reduce the lifespans of the components. To understand this synergic behaviour, ...
Computational fluid dynamics modelling and simulation of an inclined horizontal axis hydrokinetic turbine
(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 ...
Comparison of sliding and overset mesh techniques in the simulation of a vertical axis turbine for hydrokinetic applications
(MDPI, 2021)
The application of Computational Fluid Dynamics (CFD) to energy-related problems
has increased in the last decades in both renewable and conventional energy conversion processes.
In recent years, the application of CFD ...
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. ...
Influence of particle mass fraction over the turbulent behaviour of an incompressible particle-laden flow
(MDPI, 2021-10-21)
The presence of spherical solid particles immersed in an incompressible turbulent flow was
numerically investigated from the perspective of the particle mass fraction (PMF or φm), a measure
of the particle-to-fluid mass ...
Modelling the wall collision of regular non-spherical particles and experimental validation
(The Amarican Society of Mechanical Engineers (ASME),, 2014)
The importance of numerical calculations (CFD) for supporting the optimization and lay-out of industrial processes involving multiphase flows is continuously increasing. Numerous processes in powder technology involve ...
Application of the CUDA technology to the solution of fluid dynamics problems
(Universidad Autónoma de Occidente, 2014-06)
Este trabajo explora el uso de la tecnología CUDA en la solución de problemas relacionados con la dinámica de fluidos. Tres problemas clásicos de diferente nivel de complejidad: convección-difusión en un canal, la cavidad ...
