Análisis del requerimiento de aireación forzada en rápidas y elaboración de una hoja de cálculo para el diseño de aireador seleccionado

Abstract

In this thesis we have developed analysis requirement forced ventilation in steep channels and the development of a worksheet for the selected aerator. In the following chapters a brief bibliography of historical studies that allowed pose as a solution to cavitation: the device of artificial or forced aeration is denominate aerator. The basic concepts, analysis of cavitation and air concentration, and technical reports are established. Design criteria proposed by several authors arise and develop methods that allow the designated measurement a combined aerator. The implementation of a worksheet to analyze results on the possibility of risk of cavitation for different scenarios, whether for a range of flow or surface roughness of concrete according to the selected criteria: Echavez Criteria and Thoma Criteria. The worksheet also allows determining the combined aerator and determine air flow as well as dimensioning the required air duct for adding air to the water flow, and get the length which reaches under the jet aerator geometry. It is recommended that the results are corroborated by a hydraulic modeling.
