Non-swirling turbulent jet has a widespread application in industries such as cyclone separators, internal combustion engines and computational dynamics research. This study investigates the isothermal non-swirling turbulent jet under confinement conditions in an axial plus tangential type of swirl burner with a constant Reynolds number (Re) = 21,800. Computational Fluid Dynamics (CFD) simulations were conducted for a confined jet case with zero geometric swirl number (Sg = 0) using the Shear Stress Transport (SST) k-omega turbulence model. An optical quartz octagonal chamber is placed over the nozzle of the swirl burner, which is used for analyzing and visualizing the flows under confinement. The velocity contours for the mean radial, axial and tangential in vertical planes focusing on the near-exit region of the nozzle were analyzed under confined conditions. The CFD results obtained are compared to previous experimental data and the comparisons between the present study and experimental findings show a strong agreement between each other.
