Performance improvement of baffle-type solar air collector based on first chamber narrowing

A Computational Study on Thermal and Sustainability Analysis of Solar Air Heater with S and Airfoil Tabulators

“…Choose baffle angles between 600 and 1200 for maximum efficiency. Hu et al 30) tested and calculated baffle-type solar collector thermal performance. There were a total of four different collector models put through their paces under three distinct scenarios.…”

Improving Thermal Efficiency of Solar Air Collector by Creating Turbulent Flow Using New Baffles Combinations

“…The results show the effectiveness of the baffles in improving the efficiency of the collector, The study also proved that the baffles positions affect thermal efficiency, where the greatest efficiency was recorded in the fourth mode and then in the positioning of obstacles at the middle of the channel for the mode 2 and the mode 4 with a percentage of 76.61 and 90.9 , at mass flow rate m=0.0522 kg/s, while the pressure drop was very high in the mode 4, and after that the mode 2. Through the conditions of the study and taking into account all the results; we can say that the best case was mode 2. doi: 10.5829/ijee.2023. 14…”

Heat Exchange Optimization by Adding Baffles to Streaming Duct of Solar Air Collector

“…Aouissi) improve these transformers, some of them conducted experimental investigations and others used numerically by adding a new gemetrical shape of baffles [1][2][3][4] and changed the form of the duct [5][6][7][8]. Among these works, we mention the study of Hu et al [9] where prepared numerical and experimental work of the heat tranfer inside a channel divided into serval compartments, the pricipal characteristics where changed in this study is the geometrical dimension of the compartments. In the same contex Akpinar and Koçyiğit [10] conducted an experimental investigation of the heat exchange inside solar air collectoe with baffles, then compared the results with smooth plate collector.…”
