Design and Fabrication of Parabolic Trough Collector

Abstract

The objective of the research paper is to describe the phenomena of parabolic trough collector. The main purpose of our project is to increase the temperature of water by solar collector in the shape of parabolic mirror reflects the incident solar energy on the longitudinal axis of the solar collector. The difference in geometric shape of the parabolic collector helps in large way. Because of this parabolic collector achieve high outlet temperature of the working fluid. And it allows the parabolic concentrator to be integrated with solar thermal system. The thermal analysis of the collector receivers takes into consideration all modes of heat transfer; convection in to the receiver pipe, in the annulus between the receiver and the glass cover and from the glass cover to ambient air conduction through the metal receiver pipe and glass cover walls; and radiation from the metal receiver pipe and glass cover surfaces to the glass cover and the sky respectively.
