Numerical study of a confined slot impinging jet with nanofluids

BACKGROUND Heat transfer enhancement technology concerns with the aim of developing more efficient systems to satisfy the increasing demands of many applications in the fields of automotive, aerospace, electronic and process industry. A solution for obtaining efficient cooling systems is represented by the use of confined or unconfined impinging jets. Moreover, the possibility of increasing the...

Effect of Nozzle-Plate Distance on Acoustic Phenomena from Supersonic Impinging Jet

This study investigates the effect of nozzle-plate distance on the acoustic phenomena from a correctly expanded supersonic jet impinging on an inclined flat plate. In the authors’ previous study, the overall sound-pressure-level (OASPL) in the direction almost perpendicular to the plate from the impingement region became highest when the nozzle-plate distance was 15D (D, the nozzle exit diamete...

Heat Transfer of an Impinging Jet on a Plane Surface

Abstract—A cold, thin film of liquid impinging on an isothermal hot, horizontal surface has been investigated. An approximate solution for the velocity and temperature distributions in the flow along the horizontal surface is developed, which exploits the hydrodynamic similarity solution for thin film flow. The approximate solution may provide a valuable basis for assessing flow and heat transf...
