  3. Abstract:
  4. The interaction of a jet with a turbulent cross-stream is numerically investigated in this work. The interaction creates many different complex vortices which in turn interact with the main and jet flow as well as themselves. Considering a broad range of applications for the jet/turbulent boundary-layer interaction in industries, better design considerations can be achieved if good knowledge of the mixing behaviour is provided. Therefore, a close look on the near and far fields of a jet in a crossflow is provided in this work. The study is fulfilled by developing a semi-implicit pressure-based algorithm incorporated by Reynolds stress model. The results indicate that the flow topology is characterized by the development of turbulence both before and after interaction with jet. It is shown that the flow topology involves many complexities such as the vorticities at the upstream of the jet, a horseshoe wrapping around the jet, counter-rotating vortex pair in far downstream of the interaction, etc. The detected topology is then compared with that of experiment. The comparison shows that there is excellent agreement with experimental conclusions
