dc.description.abstract | The present work examines the combined influence of artificial roughness and jet impingement on the performance of solar air heater (SAH). The impingement jet SAH is roughened with discrete multi-arc shaped ribs. The experiment is performed by varying the Reynolds number (Re) from 3000 to 19,000. The different roughness parameters of multi-arc ribs varied during experimentation are as follows; relative discrete distance (D-d /L-v) from 0.27 to 0.86, relative discrete width (g(w)/H-r) from 0.32 to 1.72, relative rib height (H-r/H) from 0.025 to 0.047, relative rib pitch (P-r/H) from 0.58 to 3.1, arc angle (aa) from 35 <= to 65 <=, the streamwise pitch ratio (X/D-h) from 0.47 to 1.72 and spanwise pitch ratio (Y/D-h) from 0.46 to 0.82. The Nusselt number (Nu) and friction factor (f ) for roughened solar thermal collector are found to be 7.61 and 6.48 times higher than that of smooth channel. A thermal-hydraulic performance of 4.1 is obtained for the array of designed parameters. The correlations are also established for Nu and f using experimental data. So, utilizing roughness element along with jet impingement in SAH is found to have a substantial impact on its thermo-hydraulic performance (hthp). (C) 2022 Elsevier Ltd. All rights reserved. | - |
