Abstract :
- In the study of heat transmission, artificial
roughness is crucial. It offers a smooth absorber plate
surface to boost the airflow turbulence across it.
Artificially applied roughness additionally increase the
absorber plate’s surface area and produce vortices and
eddy in the airflow, which raises the air's heat transfer
coefficient. Varied artificial roughness with varied forms
and geometries has different heat transmission rates. In
the current study, different artificial roughness
components employed in solar air heater ducts were
studied. This paper's goal is to investigate how artificial
roughness components affect heat transfer rates with
minimal frictional cost. Tabulated forms of developed
Correlations proposed by various authors for heat
transmission and frictional factor are given. The present
article gives immense support to researchers who are
researching new artificial roughness for enhancing the
heat transmission rate in solar air heater ducts and
comparing different artificial roughness that are already
studied.
