ABSTRACT
The performance of a solar air heater roughened with sine wave baffles has been calculated in terms of effective and thermal efficiency. Relative baffle length ( relative roughness pitch
, relative height
angle of attack
, Reynolds number
, Insolation
and Temperature rise parameter
are the operational parameters. The sine wave roughened solar air heater has a higher effective and thermal efficiency than the smooth air heater. The thermal efficiency has boosted to 78%, and the effective efficiency has been improved to 70.8%. A parametric analysis has been carried out to determine the best set of parameters.
