Comprehensive performance evaluation and parametric studies of single pass solar air heater with fins and baffles attached over the absorber plate

Review of heat transfer enhancement methods: Focus on passive methods using swirl flow devices

“…Mohammadi and Sabzpooshani [8] studied single pass solar air heater with fins and baffles attached over the absorber plate (Fig. 7).…”

Comprehensive study on solar air heater with circular and V-type turbulators attached on absorber plate

“…where the convective and radiative heat transfer coefficient from the cover to the atmosphere is as follows [1]. …”

“…Heat transfer rate can be improved by creating turbulence in the flow field. Mohammadi and Sabzphoosanim [1] investigated the influence of fins and baffles attached with the absorber plate of single pass SAH and the results revealed that attaching fins and baffles effectively increases the outlet air temperature and efficiency, in comparison to a simple conventional device. Karsli et al [2] fabricated a single pass flat plate collector for drying applications and concluded that efficiency depends on solar radiation and the surface geometry of solar air collectors.…”

Performance Evaluation on Double Pass Solar Air Heater with Broken Multiple V-Type Baffles- A Review

“…Bekele et al [7] experimentally studied the effect of delta pattern obstacles mounted on one wall subjected to a constant heat flux for a rectangular channel with an aspect ratio (W=H)=10. Chamoli and Thakur [8] experimentally investigated the effect of geometrical parameters of the V-pattern perforated blocks on Nusselt number and friction factor of rectangular channel Mohammadi and Sabzpooshani [9] studied the influence of baffles' pattern mounted over the absorber plate on the performance of the upward-type single-phase solar air heater. Sriromreum et al [10] through experimentally and mathematically studied the effect of the baffle on Nusselt number and friction factor in a rectangular channel having aspect ratio (W=H)=10 fixed with the in-stage and out-phase 45_ Z-pattern baffle Chamoli [11] reviewed roughness geometries used to enhance the heat transfer in solar air heaters and keep the air in contact with the absorber and act as wings and improve Nurs of the air.…”
