The use of solar air heaters (SAH) for the collection and effective utilization of solar
radiations for thermal applications is widely reported in the literature. The current article …

For various heating applications like space heating, timber seasoning, food drying, HVAC
processes, water desalination processes, etc., where a low to medium heating source is …

The thermo-hydraulic characteristics of a solar air heater with quarter-circular ribs on the
absorber plate are studied numerically. A comparison of the three different arrangements of …

The performance of solar air heater of having a new design tubular absorber of adjacent
parallel tubes called tubular is investigated experimentally via energy, exergy, energy …

A flat plate solar air collector is a simple energy conversion system with relatively poor
performance due to low heat transfer between air and absorber. Passive heat transfer …

The solar air heater has a low convective heat transfer coefficient because the absorber
plate and moving air form a laminar sub-layer. Adding artificial roughness to the absorber …

The low heat transfer rate in a flat plate solar air heater (SAH) is due to the development of a
laminar sub-layer near the heated absorber plate. Owing to this, the plate temperature rises …

This paper presents a comprehensive review of various kinds of distinct artificial roughness
employed in rectangular and triangular duct solar air heaters to aid prospective researchers …

This work investigates the thermohydraulic performance of a porous serpentine wavy
channel solar air heater. Comprehensive illustration on the effect of fractional porous …

The roughness on the absorber surface can increase the performance of a triangular solar
air heater. This paper reveals a comparative study of smooth and rough absorber surfaces …
