Coupled turbulent flow heat and solute t

This study describes the numerical modeling of coupled turbulent fluid flow, heat, and solute transport in a continuous slab caster with an electromagnetic brake (EMBr). The objective is to enhance the design of casting machines for high casting speed and quality while minimizing defects such as macrosegregation. A continuum model is applied to solve the transport equations for total mass, momentum, energy, and species in a binary iron–carbon alloy system using the standard k–e equations, which are modified for phase changes. The methodology employs a finite-volume method to solve these conservation equations with appropriate boundary conditions, taking into account variables such as casting speed, magnetic flux density, and carbon segregation. The results outline the impacts of these process variables on velocity, temperature, and solute distributions within the system, providing valuable insights into the dynamics of the casting process. This work highlights the complexity of interactions between flow, heat, and solute transport influenced by electromagnetic forces, thus contributing to better understanding and enhancement of continuous casting processes.
