摘要：

The purpose of the current work is to investigate the flow behaviour of both a straight and a slightly rotating turbulent free jet by means of CFD and RANS-turbulence modelling. The comparison of simulation results with data from literature as well as own experimental findings is used to assess the applicability of the numerous available turbulence models for the description of the analysed flow. For the experimental analysis a three dimensional Laser-Doppler-Anemometry system is used to measure gas velocity and turbulence intensity. The results of this work clearly indicate that the quality of the CFD simulation strongly depends on the proper choice of the applied approach for turbulence description.
