A round jet discharging normally into a confined tubular swirling or nonswirling cross-flow is investigated numerically. The effect of the grid system on the flowfield prediction is analyzed from the viewpoint of numerical diffusion. The numerical diffusion is first carefully assessed. It is found that the skewness error is the major source of error in the computation. Using the measured velocity profiles as inlet boundary conditions can improve the prediction. However, the discrepancy between the predicted and measured data still exists in some regions. This is then attributed to the inadequacy of the standard k-ε turbulence model for the detail prediction of this complicated flow.
