“…5. Results and Discussion Previous research [16] Ansys software validation has been carried out by comparing the results of simulation tests with experimental data, it is found that there is a closeness of the correction factor values which tend to be the same between the simulation results and the experimental data. Thus, the simulation software used can be relied upon to predict the thermal characteristics of the collector.…”

The sun is a renewable energy source that has several advantages such as being easy to obtain, free of pollution, and available in sufficient quantities. The heat energy received by the photovoltaic can cause an increase in surface temperature, resulting in a decrease in electrical efficiency. One of the efforts to increase photovoltaic electrical efficiency is using air cooling, by adding absorber fins or thermal photovoltaic (PV/T). The lapping type fin has superior performance in reducing the temperature of the PV module compared to the linear (conventional) fin type. The purpose of this study was to compare the performance of thermal PV using conventional fins with lapping segmentation fins carried out using the CFD approach using ANSYS Fluent. The simulation test procedures include: making linear fin geometry (conventional), linear lapping and segmentation lapping, conducting mesh quality studies, and determining boundary conditions and modeling parameters. Modeling variations in the direction of airflow 0°, 15°, 30°, 45°, 60°, 75°, and 90°. The numerical simulation results show that the use of segmented lapping fins can reduce the PV surface temperature by 1.79 °C or about 4.11% compared to conventional (linear) lapping in the airflow direction of 90º (parallel to the fins). The results of this study support the use of integrated PV and passive cooling systems to reduce efficiency losses in actual conditions, where there is a multidirectional airflow characteristic, which may not be advantageous for conventional heatsinks.

The ever-increasing increase in energy consumption requires great attention. Therefore, efforts need to be made to find new energy sources, such as solar energy. The absorber plate absorbs solar energy in the form of radiation, and heat is transferred by convection to the working fluid through the solar collector. Increasing the thermal efficiency of the solar air collector by modifying the absorption area using a v-corrugated absorber and also increasing the convection heat transfer coefficient by creating turbulence in the heat transfer area. Flow turbulence can be achieved by providing a disturbance in the form of a dimple in the working fluid channel above the base plate. This research was conducted utilizing numerical simulations and experiments. CFD simulation aims to obtain the most optimum ratio of ΔT/ΔP values of diameter and dimple distance using ANSYS Fluent software with a diameter variation of 6mm, 8mm, 10mm, and 45mm spacing; 50mm, and 5mm. Based on the results of CFD simulations that have been carried out on each variation of the distance and diameter of the dimple, it can be concluded that the closer the distance between the dimples, the smaller the resulting pressure drop, and the larger the diameter of the dimple, the greater the resulting temperature value. The use of a larger dimple diameter results in an increase in the heat transfer area and further increases the outlet temperature. The expected ratio is the value of the largest temperature increase and the smallest pressure drop. In the calculation of the total ratio, the dimple diameter of 10 mm with a distance of 45 mm has the highest ΔT/ΔP ratio value.
