Abstract:

The variations of flow structure and heat transfer characteristics of impinging air jets with respect to mesh solidity are compared for two mesh screen locations at small nozzle-to-plate spacings. Results show that the uniform incoming flow structure produces higher heat transfer rates in the impingement region. The heat transfer enhancement largely depends on nozzle-to-plate spacing, mesh solidity, and jet Reynolds number. The mechanism of heat transfer enhancement is analyzed in light of the field synergy principle.
