Abstract EN
An experimental investigation has been carried out to study the effect of delta-shaped obstacles mounted on the absorber surface of an air heater duct with an aspect ratio 6 : 1 resembling the conditions close to solar air heaters.
This study encompassed the Reynolds number (Re) ranging from 3400 to 27600, longitudinal pitch of the obstacle (Pl/e) varied from 3/2 to 11/2, and relative obstacle height (e/H) varied from 0.25 to 0.75.
The relative obstacle transverse pitch (Pt/b)=7/3 and the angle of attack of flow on obstacle = 90° are kept constant during the whole experimentation.
By comparing the heat transfer data obtained from the obstacle-mounted duct with that of smooth duct under similar geometrical and flow conditions, the obstacle-mounted duct enhances the heat transfer by 3.6-times at Re=7276.82, Pl/e=3/2, and e/H=0.75.
