Physical Modelling of Flow Phenomena Bas (1)

Similitude plays a crucial role in physical modelling, particularly in representing real phenomena within the iron and steel industry. The objective of this study is to address the challenges of achieving simultaneous similitude across the Froude, Reynolds, and Weber numbers, which are essential for accurately modeling bulk and surface flow phenomena. The methodology employed includes both physical model experiments and numerical simulations to evaluate high-temperature liquid flow characteristics, given the complexities in directly observing such flows. This research reveals that while traditionally, the similitude of one or two dimensionless numbers was deemed sufficient, a more comprehensive approach can enhance the accuracy in representing real flow phenomena. The results indicate that achieving all pertinent dimensionless number similitudes is challenging but not impossible, thus providing valuable insights for optimizing water model experiments in the context of molten steel flow. This study underscores the significance of considering multiple dimensionless numbers to improve physical modeling accuracy for complex industrial processes.
