Abstract
Due to their thermal and mechanical properties, the volume recipients of the honeycomb volume have developed as promising candidates for the concentration of solar energy applications, which enables the efficient heating of liquids. Despite their potential, the challenges in optimizing the canal design and the operating conditions remain in order to improve thermodynamic performance. This study identifies construction and operating configurations, which maximize the thermodynamic performance and structural reliability of silicon carbide -honeycomb -volume -volumetry recipients and focus on thermal efficiency and safety factor. We have used a multi-lens-optimization approach by integrating the dynamics of the computer fluid, heat transfer and thermal voltage analysis. In order to optimize the calculation efforts, the Taguchi method was used, which reduces the number of the required simulations and at the same time maintained a relative error below 5 %. A critical ratio of mass flow to absorbed performance ratio of 5 × 10–6 (KG/s)/W was identified, through which thermal efficiency stabilizes and provides practical guidelines for operational optimization. The optimal configuration achieved thermal efficiency of 89.3 % and a safety factor of 87.3 % with a channel width of 3 mm, a thickness of 0.3 mm, a static outlet pressure of –70 Pa and a radiation flow of 650 kW/m2. These results determine a robust framework for the optimization of honeycomb recipients in order to take into account the thermal and structural performance and at the same time maintain simplicity in the manufacturing processes.
