This study explores the enhancement of thermal performance by disrupting laminar sublayer through use turbulence promoters on surface a heated plate. The focus is investigating how changes in several geometrical parameters V-rib combined with collective ring impact fluid flow and heat transfer properties within flat plate solar collector. Computational methods validated models, range Reynolds numbers (4000–20000) were employed to conduct comprehensive CFD analysis, examining dynamics transport properties. specifically examines influence various parameters, including relative V ratio (WD/WVR) ranging from 3.0 6.0, Ratio pitch height (PVR/HVR) 45.33 78, (HVR/Dh) 0.0238 0.0368. High friction factor (f) values observed at settings WD/WVR, PVR/HVR, HVR/Dh 45.33, 0.0368, respectively. Of significance, findings indicate that both thermohydraulic (THP) Nusselt number (Nu) peak when are set 5.0, 63.33, 0.0325, optimal configuration demonstrates potential maximize overall system efficiency.

Performance of Double‐Pass Storage Solar Air Heater Using Two Types of Porous Media and Fin Plate

Energy Storage, Год журнала: 2025, Номер 7(4)

Опубликована: Апрель 22, 2025

ABSTRACT As a result of the climate changes occurring on planet and carbon emissions they cause, solar energy systems must be developed in order to achieve greater efficiency. This study examines performance double‐pass air heaters (DPSAH) with without porous media under forced convection. Two types media, glass balls river gravel, were tested. The results showed that heater model DPSAHM‐1, achieved up 91.5% thermal efficiency summer, outperforming DPSAHM‐2 by 5%–10%. These findings highlight potential improve heat transfer heaters. Fins added both sides absorber models increase area enhance coefficient. Experiments conducted during summer winter, compared same conditions. Consequently, DPSAHM‐1 proves more effective than airflow applications is suitable for high‐temperature applications, while appropriate other
