Abstract

To explore the heat and fluid flow characteristics of normally impinging round air jet, a large eddy simulation (LES) of the jet flow at a jet-issuing Reynolds number of 4400 for a orifice-to-plate distance equal to five jet nozzle diameters was encompassed using a computer code OpenFoam. A comparison with existing experimental and numerical results was made. It was found that the LES predicted mean Nusselt number is favorably distributed in the radial direction, indicating that the LES has application potential in predicting impinging jet flows at conditions with an increased Reynolds number and a varying orifice-to-plate distance.
