Key Points

This work aims to investigate a novel solar air heater designed to enhance both heat transfer area and coefficient using various block shapes.
Utilized computational fluid dynamics to analyze thermal performance of different block shapes.
Compared various block configurations: rectangular, forward-chamfered, backward-chamfered, and triangular.
Assessed thermal-hydraulic performance at various Reynolds numbers.
Backward-chamfered block enhanced heat transfer by 1.61 times compared to smooth fin channel.
Rectangular, forward-chamfered, and triangular blocks improved heat transfer by factors of 1.52, 1.46, and 1.54, respectively.
Backward-chamfered block outperformed others below Reynolds numbers of 6000, while rectangular block excelled above 9000.
