Analysis of the Flow in a Typified USBR II Stilling Basin through a Numerical and Physical Modeling Approach

Macián Pérez, Juan Francisco; García-Bartual, Rafael; Huber, Boris; Bayón, Arnau; Vallés-Morán, F. J. (MDPI AG, 2020-01)

[EN] Adaptation of stilling basins to higher discharges than those considered for their design implies deep knowledge of the flow developed in these structures. To this end, the hydraulic jump occurring in a typified United ...
Assessment of the Performance of a Modified USBR Type II Stilling Basin by a Validated CFD Model

Macián-Pérez, Juan Francisco; Vallés-Morán, F. J.; García-Bartual, Rafael (American Society of Civil Engineers, 2021-11-01)

[EN] The adaptation of existing dams is of paramount importance to face the challenge posed by climate change and new legal frameworks. Thus, it is crucial to optimize the design of stilling basins to reduce the hydraulic ...
Caracterización de curvas de gasto en desagües profundos de presas mediante modelado CFD

Bayón, Arnau; Macián Pérez, Juan Francisco; Río, Felipe; Conesa, Francisco José; García-lorenzana, Daniel (International Association for Hydro-Environment Engineering and Research (IAHR), 2018)

[EN] The flow in dam bottom outlets constitutes a complex phenomenon due to its extraordinary dimensions and singularities, as well as to the dramatic consequences of an eventual failure. A numerical methodology is presented ...
Characterization of Structural Properties in High Reynolds Hydraulic Jump Based on CFD and Physical Modeling Approaches

Macián Pérez, Juan Francisco; Bayón, Arnau; García-Bartual, Rafael; López Jiménez, Petra Amparo; Vallés-Morán, F. J. (American Society of Civil Engineers, 2020-12-01)

[EN] A classical hydraulic jump with Froude number (Fr1=6) and Reynolds number (Re1=210,000) was characterized using the computational fluid dynamics (CFD) codes OpenFOAM and FLOW-3D, whose performance was assessed. The ...
Diseño de instalaciones hidráulicas experimentales con apoyo de la dinámica de fluidos computacional (CFD)

Bayón, Arnau; Vallés-Morán, F. J.; Macián Pérez, Juan Francisco; López Jiménez, Petra Amparo (International Association for Hydro-Environment Engineering and Research (IAHR), 2017)

[ES] La cuantificación de pérdidas de carga causadas por elementos singulares en instalaciones hidráulicas no puede realizarse determinísticamente, por lo que debe llevarse a cabo su ensayo en laboratorio. No obstante, ...
Experimental Characterization of the Hydraulic Jump Profile and Velocity Distribution in a Stilling Basin Physical Model

Macián Pérez, Juan Francisco; Vallés-Morán, F. J.; Sánchez Gómez, Santiago; De-Rossi-Estrada, Marco; García-Bartual, Rafael (MDPI AG, 2020-06)

[EN] The study of the hydraulic jump developed in stilling basins is complex to a high degree due to the intense velocity and pressure fluctuations and the significant air entrainment. It is this complexity, bound to the ...
Generación de resaltos hidráulicos de alto número de Froude a partir de regímenes rápidos emulsionados. Una investigación experimental

Vallés-Morán, F. J.; Nacher Rodriguez, Beatriz; Bayón, Arnau; Macián Pérez, Juan Francisco; Marco Segura, Juan Bautista; López Jiménez, Petra Amparo (Universidad de Córdoba, 2015-10-23)

[ES] En el caso de la modelación física descrita en esta comunicación, los primeros ensayos de laboratorio se llevaron a cabo en un dispositivo experimental diseñado ad hoc para la generación de este tipo de resaltos. Sin ...
Numerical and physical modelling approaches to the study of the hydraulic jump and its application in large-dam stilling basins

Macián Pérez, Juan Francisco (Universitat Politècnica de València, 2020-09-02)

[ES] El resalto hidráulico constituye uno de los fenómenos más complejos con aplicación en el campo de la ingeniería hidráulica. Por un lado, las propias características del resalto, entre las que se encuentran las grandes ...
