Abstract

Abstract

Due to the heating of the fluid, it decrease its density and thus becomes lighter. That is why a flow of hot fluid appears that rises through the tube towards the storage tank. At the same moment the cold fluid descends and thus a natural circulation of the fluid is established. In this work, a relationship is obtained to determine the flow based on the different variables involved in the process. From this, the influence of the angle of inclination and the length diameter relationship of the tube is obtained.

Key words: collector, thermosiphon, solar energy

Resumen

Debido al calentamiento del fluido, este disminuye su densidad y con ello se hace más liviano. Debido a esto surge el movimiento del fluido, o sea, el fluido menos denso (caliente) asciende hacia el tanque cumulador y el fluido más denso (frío) desciende hacia el tubo; con ello se logra la circulación natural del fluido. En este trabajo se obtuvo una relación entre el flujo que surge y las variables ángulo de inclinación del tubo respecto a la horizontal y respecto a la relación longitud /diámetro del tubo.

Palabras clave: colector, termisifón, energía solar.
