Analysis of turbulent exchange and coherent structures in the stable atmospheric boundary layer based on tower observations
(2013-11)
Article
Accés obertUsing data collected at the Spanish low troposphere research centre CIBA (Centro de Investigación de la Baja Atmósfera) and at the Cabauw Experimental Site for Atmospheric Research (CESAR) in the Netherlands, we analysed ... -
Coherent vorticity extraction in resistive drift-wave turbulence: Comparison of orthogonal wavelets versus proper orthogonal decomposition
(2011-03)
Article
Accés obertWe assess two techniques for extracting coherent vortices out of turbulent flows: the wavelet based Coherent Vorticity Extraction (CVE) and the Proper Orthogonal Decomposition (POD). The former decomposes the flow field ... -
Numerical simulation of two-dimensional turbulent dilatable flows in a fire
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-10-26)
Article
Accés obertNumerical simulations, based on the theories of computational fluid dynamics and combustion, are currently a powerful tool in the field of fire engineering. Field models allow us to analyze key aspects such as the integrity ... -
On the wake dynamics of an oscillating cylinder via proper orthogonal decomposition
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-09-02)
Article
Accés obertThe coherent structures and wake dynamics of a two-degree-of-freedom vibrating cylinder with a low mass ratio at Re=5300 are investigated by means of proper orthogonal decomposition (POD) of a numerical database generated ... -
Study and identification of coherent structures in turbulent boundary layers
(Universitat Politècnica de Catalunya, 2023-05-23)
Treball Final de Grau
Accés obertThis thesis describes the calculations and proceedings, as well as the theoretical basis behind them, to properly complete the post-process of a CFD analysis of the flow around the McDonnell- Douglas 30P30N airfoil. This ... -
Three dimensionality in the wake of the flow around a circular cylinder at Reynolds number 5000
(Elsevier, 2017-04-02)
Article
Accés obertThe turbulent flow around a circular cylinder has been investigated at Re=5000Re=5000 using direct numerical simulations. Low frequency behavior, vortex undulation, vortex splitting, vortex dislocations and three dimensional ...
