Advanced Thermal Enhancement of Flat-Plate Solar Air Collector

The growing demand for sustainable energy solutions has positioned solar energy as a key alternative to conventional fossil fuels. Among solar thermal technologies, flat-plate solar air collectors are widely recognized for their simplicity, reliability, and versatility in applications such as space heating and agricultural drying. This book investigates the thermal enhancement of flat-plate solar air collectors through passive heat transfer techniques, with particular emphasis on the use of staggered rectangular obstacles and offset fins. By combining theoretical analysis, Computational Fluid Dynamics (CFD) simulations using ANSYS Fluent, and validation against experimental data, the study demonstrates the effectiveness of these geometric modifications in improving collector performance. Particular consideration is given to the Algerian context, where abundant solar resources provide significant opportunities for the development of efficient solar thermal systems. The methodologies and results presented in this book are intended to support the design and optimization of high-performance solar collectors adapted to local climatic conditions and broader renewable energy applications.
