Physical Modelling of Flow Phenomena Bas

Similitude is essential in physical modelling to accurately represent real phenomena, specifically in the context of flow phenomena in high-temperature liquid flows typically encountered in the iron and steel industry. This study explores the necessity of corresponding Froude, Reynolds, and Weber numbers in physical models to ensure accurate simulation of bulk flow and surface interactions. Various physical model experiments and numerical simulations were employed to investigate the challenges associated with achieving simultaneous similitude across multiple dimensionless criteria, which are traditionally considered difficult or even impossible. The research findings suggest that the simultaneous fulfilment of these parameters is vital for the proper representation of flow phenomena in prototypes. The implications of these results extend to enhancing the methodologies used in full-scale experiments within the steelmaking sector, providing a clearer understanding of high-temperature liquid dynamics under varying conditions. This work ultimately contributes to advancing the knowledge base surrounding fluid dynamics in industrial applications, laying the groundwork for future research to further refine modelling techniques and accuracy in similitude application.
