摘要

火用分析是一种强大的热力学工具，它有助于计算系统的实际输出。它有助于研究人员优化粗糙的太阳能空气加热器设计，以满足当前和未来的需求。本研究采用数学模型对具有W形粗糙吸收器表面的太阳能空气加热器的工作性能进行了分析评价，并将所得结果与相同运行条件下的光滑板太阳能空气加热器进行了比较。对于不同的粗糙度参数，效率曲线被绘制为雷诺数和温升参数的不同值的函数。与具有光滑表面的太阳能空气加热器相比，具有W形粗糙表面的太阳能热空气加热器的工作效率最大增加了51%，对应于0.03375的相对粗糙度高度和大约60的肋攻角◦ . 基于工作效率，确定了W形粗糙化太阳能空气加热器的合适设计参数。

Exergy based analysis of solar air heater duct with W-shaped rib roughness on the absorber plate

Exergy analysis is a powerful thermodynamic tool and it helps in computing the actual output of a system. It helps the researchers to optimize the roughened solar air heater design to compensate the present and also the future needs. In this study, investigation on exergetic performance evaluation of a solar air heater with W-shaped roughened absorber surface analytically by employing mathematical model and the results obtained are compared with smooth plate solar air heater under same operating conditions. The exergetic eﬃciency curves has been plotted as a function of diﬀerent values of Reynolds number and temperature rise parameter for different roughness parameters. The maximum augmentation in the exergetic eﬃciency of the solar air heater with W-shaped roughened surface as compared to solar air heater with smooth surface has been obtained as 51% corresponding to the relative roughness height of 0.03375 and the rib angle of attack about 60 ◦ . Based on the exergetic eﬃciency the suitable design parameters of solar air heater with W-shaped roughened are determined.
