A simulation model is proposed to predict the turbulent jet flow exhausted from axisymmetric nozzles. The compressible Reynolds-Averaged Navier-Stokes (RANS) equations are solved using the open-source code OpenFOAM. An axisymmetric nozzle geometry with diameter of 0.508m is simulated considering two values of jet acoustic Mach numbers: 0.5 and 0.9. Numerical errors due to the spatial discretization are assessed. Sensitivity tests to the size of the computational domain and boundary conditions are also addressed. The accuracy of the simulation model is verified through comparisons with experimental data, available in the literature, for mean velocity and turbulent intensity profiles.
