Abstract:
Flow visualization including image processing and Particle Image Velocimetry (PIV) measurements is used to evaluate the flow velocity field of the acrylic solar sphere filled with oil. This generated convection flow is affected by the thickness of the sphere, the sphere size as well as the temperature. The function of the acrylic sphere which is a modern technology of concentrated photovoltaic is to gather the energy from the sun and then concentrate it in a compact area like a focal spot. This focal spot is placed and put directly above a multi-junction device that acts as a concentrator cell appliance. This appliance directly can generate an enormous rate of power that is utilized to generate more electricity rather than the power that normal photovoltaic panels (PV) can produce. The acrylic sphere is used also for a lot of industrial applications. This research paper aims to investigate the characteristics of the flow inside the sphere and explore the sphere thickness, the sphere size, and the sphere temperature effect on the flow velocity of the fluid motion. Moreover, the purpose of this study is to clarify the relationship between these parameters in order to achieve greater efficiency for power generation, therefore, improve its performance. The results showed that the sphere thickness, the sphere temperature, and the sphere size significantly change the flow structure value. It is found that the velocity increase as the sphere thickness decreases. Hence, the efficiency of the sphere increases when using lower acrylic sphere thickness, higher size, and lower liquid temperature. The output power and efficiency of the solar sphere increase with lower sphere thickness. The thinner the thickness of the acrylic layer, the higher the sunlight absorbed by the acrylic photons. Subsequently, the higher the output power, which results to get higher the efficiency.
