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 ...
Influence of VOF technique, turbulence model and discretization scheme on the numerical simulation of the non-aerated, skimming flow in stepped spillways

Bayón Barrachina, Arnau; Toro, J.P.; Bombardelli, F.A.; Matos, J.; López Jiménez, Petra Amparo (Elsevier, 2017)

[EN] An accurate description of the hydrodynamics in the non-aerated region of the skimming flow on stepped spillways is of outmost importance, particularly in small structures at large discharges. In addition, the flow ...
Modelización numérica 3D de la erosión local a la salida de obras de drenaje transversal

Cortés Buitrago, Raúl; Galán, Álvaro; Díaz, Sarai (Universitat Politècnica de València, 2019-04-30)

[EN] Culverts, which are common in linear works to reassemble the natural drainage network that such infrastructures intercept, should be able to drain catchment runoff and control local scour in heavy rainfall scenarios. ...
Numerical analysis of air-water flows in hydraulic structures using computational fluid dynamics (CFD)

Bayón Barrachina, Arnau (Universitat Politècnica de València, 2018-09-15)

The new legal regulations derived from climate change dictate that hydraulic structures must be designed to handle flood events associated with return periods up to 10,000 years. This obviously involves adapting the existing ...
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 ...
Performance assessment of OpenFOAM and FLOW-3D in the numerical modeling of a low Reynolds number hydraulic jump

Bayón Barrachina, Arnau; Valero, Daniel; García Bartual, Rafael Luis; Vallés Morán, Francisco José; López Jiménez, Petra Amparo (Elsevier, 2016-06-01)

A comparative performance analysis of the CFD platforms OpenFOAM and FLOW-3D is presented, focusing on a 3D swirling turbulent flow: a steady hydraulic jump at low Reynolds number. Turbulence is treated using RANS approach ...
