Population Balance Modeling of Bubbly Flow in a Slab Continuous Casting Mold

摘要：

　　A population balance model based on the Multiple-Size-Group (MUSIG) approach has been developed to investigate the polydispersed bubbly flow inside the slab continuous casting mold.The Eulerian-Eulerian approach is used to describe the equations of motion of the two-phase flow.Luo and Svendsen model and Prince and Blanch model are used to describe the bubbles breakup and coalescence behavior respectively.A 1/4rd water model of the slab continuous casting mold were applied to investigate the bubble distribution.Against experimental data,numerical results showed good agreement for the gas volume fraction and local bubble Sauter mean diameter.Close agreements between the predictions and measurements demonstrates the capability of the MUSIG model in modeling bubbly flow inside the continuous casting mold.
