Análisis de flujo no permanente para escenarios de operación normal y emergente en un sistema de conducción de alta carga, proyectado desde la zona oriental hasta el centro-norte de la ciudad de Quito, provincia de Pichincha

Abstract

This work analyzes a conduction system with a route through mountainous areas or countries crossed by the Andean Mountain range. We define it as a high load conduction system due to the difference in level, since it considers the location of the catchment sites that can be found at very high elevations and that must transport flows to sites with lower elevations. Normal and emergent operation scenarios are considered in order to control overpressure in the conduction system. Prior to the simulation in non-permanent regime, diameters were determined by means of the analysis of non-permanent regime, with the purpose of obtaining greater efficiency in terms of flow transport through the conduction and its branches. This research seeks to define alternatives for the operation of control, purge and air valves using different closing and opening patterns, through the modeling and analysis of unsteady flow, in order to obtain adequate operating conditions to avoid overpressure and underpressure in the pipeline, ensuring that the pipe thicknesses withstand the working pressures. The modeling will be performed in the HAMMER program.
