| چکیده | ||
| Artificially roughened surface is a comon method to enhance the heat transfer in a flow passage. Energy, exergy and economic analysis of solar air heaters with different roughness geometries have been done. To improve the performance of the solar collector, 4 different types of roughness on the absorber plate have been used. It was found that the most efficient roughness is Discrete V Rib and the least expensive roughness is U-Shape turbulator. NSGA II and TOPSIS algorithms used to select the best roughness geometry. | ||
