Experimental Investigation of the Thermal Performance of Vacuum Tube Solar Collectors (VTSC) Using Alumina Nanofluids
The enhancement of the thermal performance of Vacuum Tube Solar Collectors (VTSC) was studied by using alumina nanofluid as working fluid. VTSC is a simple and commonly utilized type of collector. This study established the heat transfer experimental model of all glass VTSCs used in a forced-circulation solar water heating system using alumina nanofluid as base fluid. Al2O3 (with an average par...

متن کاملNanofluid Types, Their Synthesis, Properties and Incorporation in Direct Solar Thermal Collectors: A Review
The global demand for energy is increasing and the detrimental consequences of rising greenhouse gas emissions, global warming and environmental degradation present major challenges. Solar energy offers a clean and viable renewable energy source with the potential to alleviate the detrimental consequences normally associated with fossil fuel-based energy generation. However, there are two inher...
