Abstract

A numerical prediction of the mean velocity distribution of a plane air jet issuing into the quiescent environment is conducted using the Standard k- , Realizable, k- and SST turbulent models. Different size meshes of approximately 8000, 1,760,000, and 5,000,000 grid points were used to guarantee the independence of the simulated flow from the mesh size factor. Various jet flow cases with Reynolds number based on the bulk mean velocity and the size of the inlet of 1500, 3000, 4400, 7100 and 10000 were modelled using the ANSYS-Fluent CFD software. A comparison of the simulated results with previous experimental measurements conducted using a hot wire anemometer showed relatively better agreement of the simulated velocity field with the experimental data when the Standard k-epsilon model was used, however the SST was tested only for the case of Reynolds number 1500 and it performed the best.
