Numerical Investigation of Roughened Solar Air Heater

The book explores the increasing need for energy-efficient thermal systems due to dwindling conventional energy resources, highlighting solar energy as a viable alternative. It focuses on the flat plate solar collector, a cost-effective heat exchanger for air heating, and discusses its operational principles, including the challenges posed by low heat transfer coefficients. The application of artificial roughness on the absorber plate is presented as an innovative solution to enhance the thermal performance of solar air heaters, making them more effective in energy collection and storage.
