Experimental Analysis of Heat Transfer and Thermal Performance of Parabolic Type Solar Collector with Ribbed Surface Texture for Clean Energy Extraction

Abstract

Copper plain tubes with ribbed surface texture have been tested in a solar water heater, The use of solar power is an ideal solution to meet future energy needs. Solar collectors aid in improving thermal applications by generating more energy for a green environment. This paper examines the performance of a Parabolic Type Solar Collector (PTSC) heater that uses a plain tube with ribbed surface texture tube channels. The performance of the solar water heater has been evaluated in experimental analysis for a green environment. Furthermore, the most important variables are solar radiation intensity and feed water flow rate (1.0 kg/min to 5.0 kg/min). Test data such as the experimental outcome of the suggested method enhances thermal efficiency, friction factor; convective heat transfer, Reynolds number, and the Nusselt number have been used to generate parametric values for parabolic plate solar water heaters. At a flow rate of 4 kg/min, the thermal efficiency was improved by about 28.25 %, the friction factor increased by about 0.23 %, the convective heat transfer coefficient was improved by 24.22%, the Nusselt number was improved by about 26.32 %, which is 8.25% greater than that of the plain tube plain surface.
