A 2/5 scale model with a transparent plastic sheet was built based on Froude criterion in which eight cases were studied by PIV technique, maintaining a constant gas flow rate of 596 ml/min and only varying the gas curtain position. The results permitted to get Residence Time Distribution (RTD) curves, and from the data processing it was found that combining Turbulence Inhibitor (TI) with the adequate gas curtain position it is enhanced the plug volume. The case VII presented the best results increasing the plug volume in 131.85 % in comparison with the de case IV which was taken as the reference one
