Energetic Performance Analysis of Roughened Solar Air Heater.
In the present research work an analytical model has been developed to predict the exergetic
performance of protruded shaped roughened solar air heater duct on the basis of wide range of system
and operating parameters. Optimum value of each roughness geometry parameter has been obtained on
the basis of exergetic efficiency of roughened solar air heater. Design plots have also been prepared in
order to facilitate the designer for designing such type of roughened solar air heater within the
investigated range of system and operating parameters.
