摘要: Abstract This study experimentally investigates hydrodynamical and thermal characteristics of coaxial confined impinging turbulent air jets. Various values the dimensionless nozzle-to-plate distances flowrate ratio are tested for a constant total flowrate. It is shown that enhances significantly uniformity heat transfer increases average Nusselt number while increasing distance decreases intensity convective over impingement plate. For pressure distribution on plate, subatmospheric regions observed. The results obtained case also compared with those single circular jet.
