However, the literature cited above shows that there has not yet been any research into the consequences of repositioning roughness geometries to the insulation wall, opposite to the absorber plate, as illustrated in Fig.…”

“…The absorber plate could be positioned as either the upper or lower wall. For instance, absorber plates were assigned as upper walls in the work of , Leander Antony et al (2020) and Skullong et al (2018), but were assigned as lower walls in the work of Abdullah et al (2020), Alam et al (2014), Boulemtafes-Boukadoum et al (2019), Gopi et al (2021) and Korpale et al (2020).

The aim of this work is to numerically investigate the effect of mounting winglet vortex generators on different positions in rectangular-duct-type air heaters. The two investigated positions were the absorber plate and the insulation plate, opposite to the absorber plate. Four shapes of winglet vortex generator, i.e. perforated rectangular winglet vortex generators (P-RWVG), rectangular winglet vortex generators (RWVG), perforated trapezoidal winglet vortex generators (P-TWVG) and trapezoidal winglet vortex generators (TWVG), were used. Results showed that heat-transfer capability would be better if the winglet vortex generators were mounted on the opposite insulation plate in the cases of P-RWVG, RWVG and P-TWVG.

“…Researchers are finding alternate energy sources to overcome the energy crisis and to avoid the climatic change due to the burning of fossil fuels for getting energy [1]. Solar energy is one of the most effective renewable energy sources with effective intensity power of 1016W receiving on earth's surface after losses, whereas globally 1013W of electric power is required [2]. The solar collector is a kind of heat exchanger wherein heat exchange takes between a distance source and a heat transfer fluid flowing in the collector [3].…”

Solar energy is the most abundant form of energy on this planet. In Europe and other countries with relatively low temperatures, where hot water is one of the basic needs for human beings, solar collectors are used to fulfilling their needs. In this paper performance of the solar collector will be analyzed using ANSYS software. Under specific conditions, different analyses will be performed to evaluate the performance of a solar collector containing water as heat transfer fluid. A Computational Fluid Dynamics, CFD analysis will be performed to check the heat transfer capability of copper (Cu) and aluminum (Al). The surging temperature could cause deformation, so in this paper, ANSYS structural software will be used to analyze the sustainability of structure under solar heat, so the performance of each material in solar energy applications can be estimated. After these analyses, we will be able to predict the maximum output temperature accurately we can obtain at a different time of the day, and each temperature we will analyze the maximum deformation within the structure because the pipes of solar collectors are not usually too thick, so the selection of material for the pipe is crucial. The purpose of this work is to simulate the performance of solar collectors under specific conditions and understand the temperature distribution along with the collector and also analyze the deformation we can obtain at different temperatures.
