This paper aims to investigate the effects the solar radiation on the cavity receiver for the Application in the Solar Power Generator (SPG). In order to perform work the solar power generator, high concentrated solar radiations are needed. thus, investigation of heat transfer of the cavity receiver is needed to conduct max usage of solar energy with min losing of heat for performance for the Solar Power Generator (SPG), in this research, Ansys software has been conducted to perform simulation process by using experimental results as a primary data for validation purpose. The experiments were conducted to find out the suitable aperture ration (AR = d/D) and aperture position (AP = H/D) of the cavity receiver (AR = 0.5 AP = 0.53). The results that done by simulation were confident 91% with the experiments results. The simulation process is conducted for solar radiation along the wall surface (H) of the receiver for different boundary conditions of the cavity receiver.
The relationship between energy consumption and environmental pollution is evident from the exacerbation of widespread negative consequences such as climate change, including global warming, humidity, floods, earthquakes, destructive storms, and uncontrollable natural phenomena. Therefore, it is necessary to shift from fossil fuel consumption to alternative or renewable sources of energy such as solar and wind. Taking advantage of solar cell energy and investing in various fields such as electricity generation and agricultural uses such as water pumping, desalination and concentrating on their applications for the development of rural areas and their use in the development of the industrial sector. As well as encourage the private sector and capital owners to invest in solar cell energy. In our study, we analyze the best solar cell power stations in Iraq. Three cities selected across the country, providing data on distributions of solar energy and the density of electricity generated. Therefore, the research included a methodology suitable for the subject. This research aims to detect the importance of solar energy and how to exploit it through mathematical equations concerning the distributions and density to reach the possibility of the minimum solar energy utilization and then reach the preferred location for the construction of solar cell stations in the study area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
