A computational model for residual life assessment of dents generated by explosive loads in pipelines
(2003)The present work develops a finite elements computational model that describes the process of dynamic deformation in pipelines under explosive loads. The mechanical response of the material is modeled by means of an ... -
A Structure-from-Motion Pipeline for Generating Digital Elevation Models for Surface-Runoff Analysis
(Institute of Physics Publishing, 2019)Digital Elevation Models (DEMs) are used to derive information from the morphology of a land. The topographic attributes obtained from the DEM data allow the construction of watershed delineation useful for predicting the ... -
A structure-from-motion pipeline for topographic reconstructions using unmanned aerial vehicles and open source software
(Springer Verlag, 2018)In recent years, the generation of accurate topographic reconstructions has found applications ranging from geomorphic sciences to remote sensing and urban planning, among others. The production of high resolution, ... -
Computational fluid dynamics for sub-atmospheric pressure analysis in pipe drainage
(Taylor and Francis Ltd., 2019)The occurrence of sub-atmospheric pressure in the drainage of pipelines containing an air pocket has been known as a major cause of several serious problems. Accordingly, some system malfunction and pipe buckling events ... -
Concerning Dynamic Effects in Pipe Systems with Two-Phase Flows: Pressure Surges, Cavitation, and Ventilation
(Cartagena de Indias, 2022-07-31)The risks associated with unsteady two-phase flows in pressurized pipe systems must be considered both in system design and operation. To this end, this paper summarizes experimental tests and numerical analyses that ... -
Different Experimental and Numerical Models to Analyse Emptying Processes in Pressurised Pipes with Trapped Air
(Cartagena de Indias, 2023-06-29)In hydraulic engineering, some researchers have developed different mathematical and numerical tools for a better understanding of the physical interaction between water flow in pipes with trapped air during emptying ... -
Effect of a commercial air valve on the rapid filling of a single pipeline: A numerical and experimental analysis
(MDPI AG, 2019)The filling process in water pipelines produces pressure surges caused by the compression of air pockets. In this sense, air valves should be appropriately designed to expel sufficient air to avoid pipeline failure. Recent ... -
Emptying operation of water supply networks
(MDPI AG, 2017)Recently, emptying processes have been studied in experimental facilities in pipelines, but there is a lack regarding applications in actual pipelines, which permits establishing the risk of collapse because of sub-atmospheric ... -
Experimental and numerical analysis of a water emptying pipeline using different air valves
(MDPI AG, 2017)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 ... -
Quasi-static flow model for predicting the extreme values of air pocket pressure in draining and filling operations in single water installations
(Cartagena de Indias, 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 ... -
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 ... -
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 ...
