Abstract
The use of artificial baffles is an effective passive method for enhancing heat transfer in solar air heaters (SAHs). This study numerically investigates the thermo-hydraulic performance of a channel equipped with trapezoidal baffles. Using Computational Fluid Dynamics (CFD), the study analyzes the effect of the relative pitch (P/W) of the baffles and varying inlet velocities (v = 2 to 6 m/s) on the Nusselt number ratio (Nu/Nu0), friction factor ratio (f/f0), and the overall Thermo-Hydraulic Performance Factor (TPF). The results indicate that the introduction of trapezoidal baffles disrupts thermal stratification but increases pressure drop. The model with a relative pitch of P/W = 0.105 (Model P3) demonstrated the optimal balance between heat transfer enhancement and flow resistance, achieving the highest TPF.
This study employs Computational Fluid Dynamics (CFD) simulations to evaluate the thermo‐hydraulic performance of a solar air heater (SAH) equipped with a sinusoidal absorber plate and either arc‐ or sinusoidal baffles. The novelty lies in combining a sinusoidal absorber surface with different baffle geometries and...
