Análisis del golpe de ariete en un sistema de distribución de agua

Twyman, John (Universitat Politècnica de València, 2017-04-28)

[EN] The solution to water hammer in a water distribution system (WDS) is shown by applying three hybrid methods (HM) based on the Box’s scheme, McCormack's method and Diffusive Scheme. Each HM formulation in conjunction ...
Análisis implícito del flujo transitorio de agua con aire disuelto

Twyman, J. (Universitat Politècnica de València, 2018-01-30)

[EN] The implicit finite-difference method (IFDM) for solving a system that transports water with dissolved air using a fixed (or variable) rectangular space-time mesh defined by the specified time step method is applied. ...
Diseño de la nueva conducción Subijana-Nanclares para el abastecimiento de emergencia a la planta de tratamiento de Araka (Vitoria)

Izaga Olabarrieta, Ibai (Universitat Politècnica de València, 2017-10-23)

[EN] This work has been developed in the company LKS Ingeniería S.Coop, an engineering located in the Basque Country that has been consolidating in the sector to be a benchmark in various fields, as well as in hydraulic ...
Experimental and Numerical Analysis of a Water Emptying Pipeline Using Different Air Valves

Coronado-Hernández, Oscar Enrique; Vicente S. Fuertes-Miquel; Besharat, Mohsen; Ramos, Helena M. (MDPI, 2017-02)

The emptying procedure is a common operation that engineers have to face in pipelines. This generates subatmospheric pressure caused by the expansion of air pockets, which can produce the collapse of the system depending ...
Hydraulic transient in residential buildings with a direct pump connection

Soriano Olivares, Javier; Arregui de la Cruz, Francisco; Espert Alemany, Vicent B.; García-Serra García, Jorge (Taylor & Francis, 2014-12-20)

This paper consists of an experimental and numerical study into transient behaviour in a residential building. The analysed effects occur by centrifugal pumps when they start with a direct supply (fixed-speed pumps are ...
PATs Operating in Water Networks under Unsteady Flow Conditions: Control Valve Manoeuvre and Overspeed Effect

Pérez-Sánchez, Modesto; López Jiménez, Petra Amparo; Ramos, Helena M. (MDPI AG, 2018-04)

[EN] The knowledge of transient conditions in water pressurized networks equipped with pump as turbines (PATs) is of the utmost importance and necessary for the design and correct implementation of these new renewable ...
The crucial importance of air valve characterization to the transient response of pipeline systems

Tasca, Elias; Karney, Bryan; Fuertes-Miquel, Vicente S.; Dalfré Filho, José Gilberto; Luvizotto Jr., Edevar (MDPI AG, 2022-09)

[EN] Air valves are often crucial components in an air management strategy for pressurized water conveyance systems. However, the reliability of characteristic curves of air valves found in product catalogs is quite variable. ...
Una nueva aproximación para la evaluación del golpe de ariete incluyendo la condición inicial de presurización de la instalación y del fluido

Kaless, G. (Universitat Politècnica de València, 2016-04-29)

[EN] The water hammer phenomenon is well known since the 19th century, while its mathematical formulation, by means of differential equations, is due to works of researchers such us Allievi (1903) and others from the ...
Unsteady Friction Modeling Technique for Lagrangian Approaches in Transient Simulations

Zeidan, Mohamad; Ostfeld, Avi (Editorial Universitat Politècnica de València, 2024-03-06)

[EN] This study tackles the problem of simulating the head damping effect in transient flows when modeled in the Lagrangian approach rather than Eulerian. The Lagrangian approach normally requires orders of magnitude fewer ...
