Transient phenomena during the emptying process of a single pipe with water–air interaction
(Taylor and Francis Ltd., 2019)
Emptying pipelines can be critical in many water distribution networks because subatmospheric pressure troughs could cause considerable damage to the system due to the expansion of entrapped air. Researchers have given ...
Subatmospheric pressure in a water draining pipeline with an air pocket
(Taylor and Francis Ltd., 2018)
An air pocket’s behaviour inside of a pipeline during transient conditions is of great importance due to its effect on the safety of the hydraulic system and the complexity of modeling its behaviour. The emptying process ...
Backflow air and pressure analysis in emptying a pipeline containing an entrapped air pocket
(Taylor and Francis Ltd., 2018)
The prediction of the pressure inside the air pocket in water pipelines has been the topic for a lot of research works. Several aspects in this field have been discussed, such as the filling and the emptying procedures. ...
Rigid water column model for simulating the emptying process in a pipeline using pressurized air
(American Society of Civil Engineers (ASCE), 2018)
This paper presents a mathematical model for analyzing the emptying process in a pipeline using pressurized air. The rigid water column model (RWCM) is used to analyze the transient phenomena that occur during the emptying ...
CFD and 1D simulation of transient flow effect on air vessel
(BHR Group Limited, 2018)
The estimation of unsteady parameters in two-phase condition is crucial for the safety and reliability of the hydraulic systems. There are plenty of one-dimensional (1D) simulation tools for unsteady flow estimation being ...
Cambios en el periodismo y su impacto en la autonomía profesional: evidencia del estudio The Worlds of Journalism en siete países de América Latina
(2022-12-28)
Los debates en torno al futuro del periodismo posibilitaron numerosas investigaciones sobre sus cambios en el nuevo contexto hiperdigitalizado. Sin embargo, se desconoce su impacto en la libertad de prensa, específicamente ...
Effect of the non-stationarity of rainfall events on the design of hydraulic structures for runoff management and its applications to a case study at Gordo Creek watershed in Cartagena de Indias, Colombia
(MDPI AG, 2018)
The 24-h maximum rainfall (P 24h-max ) observations recorded at the synoptic weather station of Rafael Núñez airport (Cartagena de Indias, Colombia) were analyzed, and a linear increasing trend over time was identified. ...
Professional Autonomy and Structural Influences: Exploring How Homicides, Perceived Insecurity, Aggressions Against Journalists, and Inequalities Affect Perceived Journalistic Autonomy in Colombia
(2020)
Journalistic autonomy has been studied more frequently in countries with secure democracies in terms of journalists’ perceptions of freedom and independence to work in the midst of the controls, pressures, and influences ...
Quasi-static flow model for predicting the extreme values of air pocket pressure in draining and filling operations in single water installations
(2020)
Inertial models have been used by researchers to simulate the draining and filling processes in water pipelines, based on the evolution of the main hydraulic and thermodynamic variables. These models use complex differential ...
Optimal Economic–Environmental Operation of BESS in AC Distribution Systems: A Convex Multi-Objective Formulation
(2021-12-10)
This paper deals with the multi-objective operation of battery energy storage systems
(BESS) in AC distribution systems using a convex reformulation. The objective functions are CO2
emissions, and the costs of the daily ...
