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.

已经进行了一项实验研究，以通过吸收板上的挡板整合人工粗糙度来提高太阳能空气加热器的性能。本文研究了用V up多孔隔板粗糙化的太阳能空气加热器（SAH）的热和能量矩阵分析。在有挡板和无挡板的情况下，分析了各种质量流量对SAH的影响。对诸如排气温度，有用能量（热）增益和热效率的实验输出进行了评估，以确认性能的提高。发现带挡板的吸收器板SAH在质量流量为0.0346 kg / s时具有89.3％和1321.37 W的最大热效率和有用的能量增益，比没有挡板的SAH高出13％和12％。该结果表明，对于所研究的参数，V字形肋在流动布置中提供了比光滑板SAH更好的热性能。还对SAH系统的能量矩阵分析和二氧化碳减排进行了分析。
