Improving Thermal Performance of Solar PTC Using Internal Finned Structure
Аннотация
In the given work, the idea of simple and fumed absorber tubes of a parabolic trough solar collector (PTC) are taken into account and numerically analysed. The 3D numerical models are performed with the help of a COMSOL Multiphysics 6.1 software. This has also been done in order to research on temperature distribution, useful energy gain and thermal efficiency of absorber tubes. A solver configuration of time dependent is provided by applying the variable input data of a solar heat flux condition to receiver tubes. As can be observed, the fumed receiver tube exhibited better performance than the conventional design. The temperature variations, useful energy gain, thermal efficiency of the receiver of Solar PTC are supplied in the discussion section of this article.
