Using both active and static technical
categories, the transmission of heat can be improved.
When compared to passive methods, which increase
turbulent conditions by adding artificial protrusions in
to the absorbent plate, active approaches show less
promise. This article evaluates the many passive heat
transfer techniques that can improve the air's convection
heat transfer coefficient. In this study, we examine the
impacts of artificial texture on the thermal
characteristics of solar heating ducts for low-pressure
drops. The work's primary focus is the mathematical
and experimental exploration of heat conduction in the
solar system's framework channels, without and
alongside artificial protrusions. Additionally, different
duct designs for solar thermal water heaters were
investigated for both scientific and experimental uses in
a range.
