The turbulent mixing of jet flows is one of the important problems of turbulent shear flow due to its application in combustion process involving fuel-oxidizer combinations such as hydrogen-air and methane-air. Fluid dynamics of opposed jets is not completely clarified as there are questions unanswered about flow stability and structure. In the present work, three-dimensional numerical simulations were conducted to study flow and mixing characteristics of turbulent opposed-jets. The numerical simulations were carried out with a finite volume CFD code. Turbulence is treated with the two equation model, the k-ε model. Nozzle diameter (d) and nozzle separation (W) are kept constant and equals to 32mm. Also, different jet velocities (Uj) have been examined corresponding to Reynolds numbers of 4500 to 12,000. Both confined and unconfined cases were simulated.
