Optimization of parabolic trough solar collectors

Solar Energy, 1982
Abstract The results of a detailed optical analysis of parabolic trough solar collectors are summarized by a few universal graphs and curve fits. These graphs enable the designer of parabolic trough collectors to calculate the performance and optimize the design with a simple hand calculator.

Design of solar parabolic trough collector

2017 International Conference on Advances in Mechanical, Industrial, Automation and Management Systems (AMIAMS), 2017
In this paper, the design stages of a solar parabolic trough collector is presented. The design of prototype was done using Creo parametric 2.0 software. The design parameters are decided on the basis of analysis and its effects due to variations in the parameters. This design process will be useful in fabrication of solar parabolic trough collector.

Optical Modeling of Parabolic Trough Solar Collector

2020
In this article, the flux distribution of parabolic trough solar collector (PTSC) is performed by considering limb darkening effect in the incoming solar radiation. Inhouse model is developed using the MATLAB tool for the analysis. The effort is also made to reduce the computation time of CPU by converting the complete PTSC problem into two-dimensional

Performance simulation of a parabolic trough solar collector

Solar Energy, 2012
Abstract A new analytical model for optical performance and a modified integration algorithm are proposed and applied to simulate the performance of a parabolic trough solar collector with vacuum tube receiver. The analytical equation for optical efficiency of each point at reflector is derived first, then the optical efficiency of the system is ...

Design of Solar Parabolic Trough Collector by FEM

Volume 3: 28th Computers and Information in Engineering Conference, Parts A and B, 2008
Structural optimum design of the collector was presented in this paper by using finite element software ABAQUS incorporated with genetic optimal algorithms. In the optimization of trusses, cross-sectional areas of members were considered as variables and the maximum node displacement was used as the constraint in genetic algorithms.
