Parabolic trough solar collectors’ core are their meticulously crafted parabolic-shaped reflectors, which focus sunlight onto a focal line. This collector system is skillfully designed, using highly reflecting materials to enhance sunlight capture. The concentrated sunlight warms a fluid circling within a receiver tube along the focal line.
Due to the importance of thermal conditions inside the solar collector, it is chosen to be simulated using ANSYS Fluent software. So, in this project, we focus on heat transfer investigation on Solar collector regarding a valuable reference paper entitled “A numerical analysis of the effects of nanofluid and porous media utilization on the performance of parabolic trough solar collectors “.

Simulation Process
In the primary phase of the project, the geometry is designed using the ANSYS Design Modeler. It consists of different parts indicating opaque and glass parts, each with itw own radiative condition. Then, a high-quality mesh grid is generated using ICEM software. In total, 1144005 quadrilateral elements (Structured) were made. The Discrete Ordinates (DO) radiation model is activated to consider radiative effects. Considering a non-uniform heat flux applied to the absorber layer is important. Thus, a User-defined Function (UDF) is written.
Post-processing
As can be seen in the following figure that depicts surface heat flux, a proper non-uniform distribution is correctly applied on the bottom layer with the highest concentration in the middle. The water flows inside at 300K temperature. The heat received by the collector from the parabolic trough effectively warm up the working fluid. The solid opaque part on the top suppresses heat wasting and hastens the heating process. In some areas, it can be seen that temperature drastically increases. However, the average temperature at the outlet was reported to be 367.13K, which proves 22.3% increase.
We pride ourselves on presenting unique products at CFDLAND. We stand out for our scientific rigor and validity. Our products are not based on guesswork or theoretical assumptions like many others. Instead, most of our products are validated using experimental or numerical data from valued scientific journals. Even if direct validation isn’t possible, we build our models and assumptions on the latest research, typically using reference articles to approximate reality.
Yes, we’ll be here . If you have trouble loading files, having technical problems, or have any questions about how to use our products, our technical support team is here to help.
You can load geometry and mesh files, as well as case and data files, using any version of ANSYS Fluent.
