The effects of shroud diameter, air rate and submergence depth on the residence time distribution of steel melt due to argon shrouded stream in a tundish are studied through a cold model by the impulse response technique using a micro‐computer. All the above parameters are found to influence the proportion of surface/bottom flow and the residence times of the volumes of fluid before exiting the tundish. The effect of flow pattern on residence time is analysed in terms of the ratio peak time/delay time and the variance/square of mean residence time. Lastly, a relationship is derived between the different volume fractions and the residence time.
