Both water modeling and numerical simulation were carried out to investigate the turbulence flow in swirling chamber of a swirling flow tundish for steel continuous casting. For water modeling, the Froude and Reynolds numbers were taken as similarity criteria. For the numerical simulation, the commercial software package was used, and the simulation was carried out on orthogonal grid with k-ε two-equation turbulence model. The flow pattern and the distribution of the rotational velocity in the swirling chamber were obtained. The influence of the diameter and height of swirling chamber and the flow rate of water on linear velocity field, rotational velocity and eddy position in the chamber was systemically examined. In addition, a similarity criterion number Rt, to represent the relationship of rotational velocity between water model and physical prototype was also obtained by dimensional analysis of rotational velocity, characteristic length, volume flow rate and kinetic viscosity.
