The tundish working as a buffer and distributor of liquid steel between the ladle and continuous casting (CC) moulds. It plays a vital role in the performance of CC machine, Solidification of liquid steel and quality of productivity. Therefore it is necessary to control the flow pattern, heat transfer and inclusion particle movement of molten steel in the tundish [1]. Hence this paper targets to study the performance of tundish by studying water volume fractions and validated against the Planar Laser Induced Fluorescence (PLIF) results obtained from available literature. The variation of time dependent concentration field is measured by PLIF. Due to special calibration procedure of the PLIF system the optical, geometrical and physical parameters do not have to be determined analytically, thus leading to reliable results. The experiments have shown that the mixing process correlates with the quasi steady state flow pattern. Such information is important in steel production because the number of mixed slabs produced during sequence casting with a grade change is closely related to the mixing of the tundish melt. Hence in this paper PLIF measurements are used to validate numerical solutions of the mixing processes in water models of metallurgical reactor [2].
