Generation of Thermal Profile of Nano Carbon and Daturastramonium Extract Coated Solar Absorber

Abstract

Generation of thermal profile of nano carbon and Datura Stramonium extract coated solar absorbers is mandatory for their effective photo thermal applications. In this connection, the present research was devoted (i) To generate thermal profile of single coated solar absorber in outdoor conditions (ii) To generate thermal profile of double coated solar absorber in outdoor conditions and (iii) To evaluate the thermal performance of solar collector with the prepared solar absorbers in field conditions. In continuations, the single and double coated solar absorbers were kept in outdoor conditions and the thermal profile of the absorbers was generated. The solar collector with the coated absorbers was kept in field conditions and its thermal performance was experimentally assessed. It was found that the temperature enhancement of fluid on single coated solar absorber in outdoor conditions varied from 2.60C to 9.10C. It was also found that the temperature enhancement of fluid on double coated solar absorber in outdoor conditions ranged between 3.20C and 10.60C. It was as well found that the thermal performance of solar collector with single and double coated absorbers was 65% and 67.2% respectively. It could be concluded that the end user would prefer the solar collector with either single or double coated absorbers as per temperature requirements of fluid in photo thermal applications.
