Analysis of parabolic trough collector

This post was originally published on this site Publication date: Renewable Energy, Volume Author s: Assad Abstract A parabolic trough is defined as a type of solar thermal collector that is straight in one dimension and curved as a parabola in the other two, lined with a polished metal mirror.

Enhancing the thermal efficiency of this collectors is one of the major challenges of developing and growing of parabolic trough solar thermal power plants. Ferrofluids were proposed as a novel working fluid for industrial applications, due to their thermal performances.

In this study, the convective heat transfer of Fe3O4-Therminol 66 ferrofluid under magnetic field 0— G is evaluated using computational fluid dynamics.

Numerical analysis first validated using theoretical results, and then a detailed study is conducted in order to analyze the effect of the magnetic field on different parameters. The result demonstrated that using magnetic field can increase the local heat transfer coefficient of the collector tube, thermal efficiency as well as output temperature of the collector.

In addition, increasing the volume fraction of nanoparticle in the base fluid and intensity of magnetic field increased the collector performance.Concentrating solar collectors use shaped mirrors or lens to provide higher temperatures that flat plate collectors.

Heliostats are tracking mirrors that reflect solar energy onto a fixed target. Design analysis of solar parabolic trough thermal collectors.

Analysis of parabolic trough collector

() Used a thermal model for analysis of parabolic trough collector receiver. The model was validated using known performance. Nise's Control Systems Engineering takes a practical approach, presenting clear and complete explanations.

Real world examples demonstrate the analysis and design process, while helpful skill assessment exercises, numerous in-chapter examples, review . HEAT TRANSFER ANALYSIS AND MODELING OF A PARABOLIC TROUGH SOLAR RECEIVER IMPLEMENTED IN ENGINEERING EQUATION SOLVER ABSTRACT This report describes the development, validation, and use of a heat transfer model implemented in (EES).

The model determines the performance of a parabolic trough solar collector. Parabolic trough collector is a type of high temperature solar concentrator collector.

These collectors have a linear parabolic shaped reflector that focuses sun radiation on a receiver at the focus of the reflector. Parabolic troughs are long parallel rows of curved glass mirrors. Solar water heating systems have a good economic payoff, and are manageable systems to install or build as a DIY project.

Some of the solar water heating designs are very simple and low cost.
