Abstract

Solar air heaters (SAHs) furnish an economical and sustainable alternative to heating air for drying and space heating purposes, using solar energy instead of fossil-fuel-based heat. This study experimentally investigates thermal and frictional features in a SAH channel fitted with enlarged-size V-baffles (B/H = 0.8) featuring staggered, racetrack-shaped perforations of constant circularity (Οˆβ€‰= 0.87). It compares their performance with that of reduced-height baffles (B/H = 0.5) and a smooth channel. The V-up configuration with B/H = 0.8 achieves the highest Nu/Nuβ‚› (heat transfer ratio) of 3.224 at S/H = 1 and the highest friction factor ratio (f/fβ‚› of 52.74) at S/H = 2, both at the maximum Re. However, despite the enhanced heat transfer, the high flow friction makes this configuration thermohydraulically suboptimal. V-down baffles (B/H = 0.5 at S/H = 1) obtain the best performance results, yielding a maximum THPP of 1.47 at Re = 8729.
