Validation Experiments in Field of Physical Modelling of Metal Bath Flow

Popis výsledku v původním jazyce

Accuracy and thus the applicability of physical modelling results in the field of metallurgical processes must respect the basic rules of similarity theory and practice between the two systems. The choice of model geometry (length) scale is one of the basic factors which must be very carefully determined. This paper deals with the assessment of the impact of the geometric scale of the physical model of a tundish on the coincidence of the simulation results. Two models of an identical operating tundish designed on the scales 0.2 and 0.25 (1:5 and 1:4) were used for the experimental study. Different boundary conditions, including changes in the geometry of the bottom without any kind of impact pad (e.g. ?Turbostop?) were used to study the correctness ofthe similarity theory between the two systems. Experiments were carried out and then compared from the perspective of permanent change (F-curve) of tracer (KCl) concentration. The results of experiments were processed by mathematical/stat
