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 ...
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 ...
Ultrasonic measurement of viscosity: Signal processing methodologies
(Universidad Autónoma de Occidente, 2019-01)
This work deals with two alternative methodologies for data post-processing resulting from the ultrasonic shear-wave reflectance method used for liquid viscosity measurement. In the shear-wave reflectance method, the ...
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 ...
Quantification of preferential concentration of colliding particles in a homogeneous isotropic turbulent flow
(Elsevier, 2019-05-24)
This paper addresses the effect of inter-particle collisions on the segregation of non-settling inertial particles in homogeneous isotropic turbulence. For this purpose, direct numerical simulations of particles in ...
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 ...
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 ...
