Abstract: In this work, experimental analysis on flow and heat transfer characteristics of different impingement jet plates is performed. The various air jet impingement plates such as, triangular shape air jets impingement plate, rectangular shape air jets impingement plate, square shape air jet impingement plate, circular shape air jets impingement plate have been analyzed for the same Reynolds number. The hydrodynamic and thermal performance is discussed to examine the overall effects of the various shapes of impingement jet plates. The results reveal that the circular impingement jet shapes provide better hydrodynamic and thermal performance than other comparable impingement jet shapes. |
Keywords and phrases: solar energy, pressure drop, impingement jets, heat transfer. |
