Diseño y construcción de una torre solar a escala para la generación de energía eléctrica : diseño y construcción de un colector de una torre solar a escala para la generación de energía eléctrica.

Abstract

The main objective of the work carried out in this document is to design and build the collector of the solar tower to scale for the generation of electrical energy, knowing the environmental characteristics such as temperature, wind speed and solar radiation. For which a mathematical model is proposed, which seeks to find the temperature of the working fluid at the collector outlet based on the collector area, the global radiation of the sector where it is located. The collector is in charge of concentrating solar energy and with it, through heat transfer mechanisms such as radiation and convection, the air that passes over the absorbing surface is heated, which produces a change in densities, this being a fluid and increasing the temperature results in an increase in air velocity. When obtaining the mathematical model, the sizing and construction of the solar collector is carried out, which consists of an absorbing surface and a transparent cover which must have a material which facilitates the passage of solar rays. With the mathematical model and the experimental data of the prototype, the errors and average errors of 10% are obtained, this being an acceptable value in thermal designs.
