Enhancement of heat transfer in the solar air heater ducts can be achieved by breaking
laminar sub-layer near the absorbing surface and can be efficiently done by employing ribs …

Lower thermal performance of conventional solar air heaters (SAH) can be enhanced by
implementing small sized roughness elements on the air-flow side of the absorber plate …

Experimental and numerical studies have been carried out to study the effect of using baffles
on the flow and heat transfer characteristics in a rectangular channel with an aspect ratio of …

Roughness is one of the effective and promising method to improve heat transfer through
the solar air heater. The cross-sectional shape of roughness provided on the absorber plate …

A numerical simulation of a solar air heater (SAH) with transverse equilateral triangular
ribbed surface is carried out. The rib-pitch (P) and rib-height (e) ratio P/e 14.29, rib height …

Ribs on the underside of the absorber plate of solar air heater enhance the convective heat
transfer rate of the air flowing through it. Several experimental and numerical investigations …

Roughening the absorber plate of a solar air heater is a convenient technique to increase
the rate of heat transfer. This study aimed to investigate the effect of discrete cylindrical …

Mechanics-related tasks often present unique challenges in achieving accurate geometric
