The present paper reports new numerical results of the mean mass transfer in a turbulent submerged round jet. A series of Large Eddy Simulations (LES) are presented at four Reynolds (Re) numbers (Re = 2492, Re = 4491, Re = 9994, Re = 19,988) and laminar Schmidt (Sc) number equal to Sc = 10. The numerical results are specially focused on their patterns in the Undisturbed Region of Flow (URF), Potential Core Region (PCR) and Fully Developed Region (FDR). The present results are compared with the previous literature concerning a two-dimensional and a three-dimensional jet, issuing from an infinitely wide slot, with the conclusion that the turbulence moments decay faster in a round jet configuration.

Abstract
The present paper reports new numerical results of the mean mass transfer in a turbulent submerged round jet. A series of Large Eddy Simulations (LES) are presented at four Reynolds (Re) numbers (Re = 2492, Re = 4491, Re = 9994, Re = 19,988) and laminar Schmidt (Sc) number equal to Sc = 10. The numerical results are specially focused on their patterns in the Undisturbed Region of Flow (URF), Potential Core Region (PCR) and Fully Developed Region (FDR). The present results are compared with the previous literature concerning a two-dimensional and a three-dimensional jet, issuing from an infinitely wide slot, with the conclusion that the turbulence moments decay faster in a round jet configuration.| File | Dimensione | Formato | |
