In steel continuous casting, flow in the mold region is related to many quality problems such as surface defects and slag entrainment. An electromagnetic braking (EMBr) system is a method to control the steel flow field to minimize defects and capture inclusions. The position of the port of the Submerged Entry Nozzle (SEN) and peak magnetic field both affect the performance of EMBr. In the present work, a multi-GPU based code, CUFLOW, is used to perform Large Eddy Simulations of turbulent flow by solving the time-dependent Navier-Stokes equations in a domain includes slide gate, SEN and mold region. The computations were first validated by comparing predicted surface velocity with plant measurements. Subsequently, seven LES simulations were conducted to study the effects of different EMBr values and SEN depths. The flow patterns in various regions are presented. The results show that applying EMBr greatly lowers top surface velocities and turbulent fluctuations.
