Abstract
Article presents results of numerical simulation of steel flow and mixing in real two strand tundish working in on of polish steelworks. In calculation different casting flow rates were tested. They were analyzed taking into account their influence on the hydrodynamic conditions occurring in reactor. AnsysFluent code was used for numerical simulation of 3D turbulent steel flow in tundish for steady and transient conditions. As a result of calculation spatial velocity fields and steel turbulence intensity were obtained. Research was complemented by residence time distribution – typical for analyzed calculated. Whereas basing on F curves the kinetic of steel mixing were estimated.
