Large Eddy Simulation on the Transient Decarburization of the Molten Steel During RH Refining Process

摘要

A mathematical model for the decarburization coupling with the transient fluid flow in RH (Ruhrstahl-Hereaeus) treatment was established. The periodicity of the flow field calculated by large eddy simulation (LES) model was analyzed. Taking 13 seconds as the flow field period, the flow field information stored in user-defined memory is read repeatedly in order in the calculation, and the transport of [C] and [O] in the molten steel coupling with LES model is realized, which greatly reduce the calculation time.
