摘要: In the present study, we compared the thermal performance of the two types of impinging jets: confinedand unconfined impinging jets. In order to obtain the thermal characteristics of impinging jets, experimentalinvestigations for air and water are conducted. The effects of dimensionless pumping powersðPpump ¼ 1: 35 1010 4 1013Þ on the Nusselt number are considered. The focus is on the cases wherethe nozzle-to-plate spacing is equal to or less than one nozzle diameter (H/d 6 1). The results show thatthe thermal performance of the …
