Numerical investigations into the sensitivity of the near field of a plane jet to the inlet boundary conditions were performed, employing both finite element and finite volume methods together with the k-'epsilon' turbulence model. The study shows that the near field is insensitive to the turbulent inlet boundary conditions when a uniform velocity profile is used. However, when a non-uniform, shear dominated velocity profile is used, the assignment of turbulent parameters has a substantial effect on the solution.
