Özet
This study aimed to investigate the thermal behavior of water flows in a solar collector equipped with zig-zag tubes. To achieve this, a numerical simulation using CFD was conducted, which is a powerful tool for analyzing fluid-flow and heat transfer. The simulation employed the finite volume method to discretize the fluid domain and the SIMPLE algorithm to solve the pressure-velocity coupling. The simulation results indicated that the shape of the tubes significantly influenced the flow behavior and overall performance of the solar collector. Specifically, the temperature profiles at various times of the day showed that zig-zagshaped tubes enhanced the heat transfer coefficient, resulting in higher temperatures within the collector. Moreover, the zig-zag design increased the residence time of the fluid inside the collector, further improving its overall efficiency. These findings highlight the potential of utilizing zig-zag-shaped tubes to optimize the performance of solar water heating systems, which could have important implications for renewable energy applications.
