“…Similar studies of Alam and Kim, 25 Ravi and Saini, 26 Sharma and Kalamkar, 27 Abuska, 28 and Ho et al 29 have also improved the efficiency of the traditional SAC by changing the absorber surface. They have demonstrated that modifying the absorber plate was a suitable method to increase the convective heat transfer rate of air.…”

“…The pertinent literature 1‐41 reveals many attempts have been made in past to improve SAC efficiency using various methods such as varying the number of glazing; changing the air gap; using different absorber plate materials; and modifying the absorber surface by incorporating selective coatings, fixing fins, or adding vortex generators. Furthermore, it has been observed that the performances of SACs with similar design configurations could be different.…”

Global interest in decreasing CO 2 emissions and depletion of fossil fuel assets has pushed the industrial sector to use more solar energy due to its abundance and clean nature. Presently, solar air collectors (SACs) are commonly employed to absorb and convert radiant energy into useful heat energy (i.e., warm air) for drying farm crops, space heating, etc. Typically, black-coated absorber plates are preferred for SACs as they help to transfer valuable heat to air flowing over the absorber plate in natural or forced convection mode. SAC can perform at a higher operating

“…Double-Pass SAHs (DPSAH) considerably increase the collector surface area and therefore offer considerable gains in heat transfer [4]. Double-Pass SAHs with crossflow [5], recycling [6], and parallel flow [7,8] are the DPSAH arrangements that were utilized as the primary factors that impacted the performance. Yadav and Prasad [9] discovered that the DPPFSAH's rate of heat gain was 8-10% higher than a smooth duct.…”

To investigate the influencing range and optimize values of different operational and system parameters on the double-pass parallel flow solar air heater's (DPPFSAH) thermal, effective, and exergetic efficiencies, an iterative method was used to analyze the governing energy equations using a theoretical model written in MATLAB based on the Nusselt number (Nu) and friction factor (f) correlations developed in the work performed earlier. A comparison between double-pass and single-pass SAHs for mathematical and experimental outcomes was conducted, and the results were found to be fairly consistent. According to the thermo-hydraulic performance indicators, similar to single-pass SAHs, perforated multi-V rib-roughened DPPFSAHs achieve optimum thermal performance for lower Reynolds numbers, which does not change much as the Reynolds number increases above 18,000. This finding can be taken into account when designing any DPPFSAH.

“…An experimental investigation conducted by Kabeel et al [19] on SACs using flat and V-corrugated absorber with PCM based energy storage showed that a collector with Vcorrugated absorber with PCM storage was 12% to 21% more efficient than a flat plate SAC with and without PCM. Effectively Ho et al [20] reported that for a V-corrugated SAC with double pass recycling, the collector performance improved at higher recycle ratios and mass flow rates compared to a conventional SAC. Kabeel et al [21] investigated SAC with flat plate, finned, baffled, and baffled fin absorber and found that the maximum efficiency of a baffled fin absorber was 83.8% at flow rate of 0.04 kg/s.…”
