An experimental study has been carried out to enhance a solar air heater’s performance by integrating artificial roughness through baffles on the absorber plate. In this paper, the thermal and energy matrices analysis of a Solar Air Heater (SAH) roughened with V up perforated baffles have been investigated. The effect of various mass flow rates on the SAH was analyzed with and without baffles. Experimental outputs like outlet air temperature, useful energy (heat) gain and thermal efficiency were evaluated to confirm the performance improvement. The baffled absorber plate SAH was found to give the maximum thermal efficiency and useful energy gain of 89.3% and 1321.37 W at a mass flow rate of 0.0346 kg/s, 13% and 12% higher than SAH without baffle. This result showed that the V up-shaped ribs in flow arrangement provide better thermal performance than smooth plate SAH for the parameter investigated. Energy matrices analysis and carbon dioxide mitigation of the SAH system were also analyzed.

The use of variable baffle solar panels for drying is the low level of heat exchange with the air in the dynamic vein of the solar panel. This weakness in such systems does not provide optimal performance or high thermal efficiency from their use. There is, however, a very noticeable improvement in heat transfer when the baffles are placed in rows in the ducts. To conduct the experiments, solar energy was simulated, the goal being to improve the relationship between temperature and thermal efficiency of a solar panel air heating plane and to use the system to reduce the time to gently dry the lemon to keep these vitamins. lemon and destinine for a sustainable therapy (the lemon promotes the absorption of calcium and in case of rhumet gill or five also to treat sinusitis, against migraine solair dryness and also for sustainable conservation and also for a sustainable medicine for a sustainable medicine.
