dc.description.abstract	Fluid dynamics of opposed jets is not completely clarified as there are questions unanswered about flow stability and structure. The achievement of high efficiency combustion requires adequate mixing between the fuel and the oxidizer. In the present work, three-dimensional numerical simulations were conducted to study mixing and combustion 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 4,500 to 12,000. Both confined and unconfined cases were simulated. Results for reacting flows of hydrogen-air flames are presented.	en_ZA
