International communications in heat and mass transfer, 2006•ElsevierA numerical analysis is conducted for turbulent flow of a rectangular free jet with an aspect
ratio of 2: 1. The computations were performed using two standard two-equation turbulence
models (the k–ε and the k–ω models). Two inflow boundary conditions were evaluated with
each model: a uniform inlet velocity profile and a profiled inlet velocity fitted to experimental
data. The results show that the k–ε model with the profiled inlet velocity succeeded in
predicting the main features of the flow, including the vena contracta and the saddle-shaped …

The results show that the k–ε model with the profiled inlet velocity succeeded in predicting the main features of the flow, including the vena contracta and the saddle-shaped velocity profiles in the near-field region, and the rate of velocity decay in the far-field region.
