Optimal forecasting of thermal conductivity and storage in parabolic trough collector using phase change materials

Abstract

Renewable energy is one of the cleaner energy generation strategies practiced all over the world to reduce environmental impacts and waste based on current sustainability in economic practices. Solar energy is one kind of renewable sources of energy practiced for different application. The thermal storage system in solar energy is one of the least practiced methods in research, and the utilization of solar energy in the thermal application is attaining higher responses and is quite possible. In this paper, solar heat generation is attained by solar parabolic trough collector using phase change materials. The ideology behind this research is to develop a thermal energy storage system using solar collectors and phase change materials. A composition mixture of MgCl2. 6H2O phase change materials used as the fluid medium in trough collector and thermal efficiency of the material is evaluated. For effective optimization, an imperialist competitive algorithm is used for optimizing the thermal efficiency of the solar collectors. The thermal efficiency of the collector is numerically experimented in the running platform of Mat Lab and executed in terms of heat gain, heat loss, and thermal efficiency of the parabolic trough collector, respectively. The efficiency of the proposed framework is 85%, and the current framework just has 80% efficiency. The heat loss in the proposed framework is lower than that of the current system, distinguished as 4200 W and 4520 W, respectively. It is shown from the research study that the proposed PCM composition is an optimal method for generating heat energy in solar parabolic trough collectors.

Modelling and optimization of phase change materials (PCM)-based passive cooling of solar PV panels in multi climate conditions

“…Solar energy, which is a clean and abundant new energy source, has broad application prospects (Rajendran et al, 2017;Amina et al, 2016). This paper elaborates on using solar energy to generate thermal energy and storage systems by proposing phase change materials as the collector fluid for the thermal energy storage system (Muruganantham and Balaji, 2021). The researcher (Shakibi et al, 2023) combines finned collectors with a nanoparticle-based phase change material (PCM) layer to enhance electricity generation in photovoltaic/thermal (PV/T) collectors.…”
