Electromagnetic (EM) induction heating of open top risers represents an energy-efficient method to preserve mass feeding whilst allowing for the use of a smaller riser and thus higher casting yield. Numerical simulation results for an ill-designed, c

While numerical models are often used in industry to evaluate the transport phenomena in solidification processes, the uncertainty in the results propagated from uncertain input parameters is rarely considered. In this work, in order to investigate t
