Abstract In order to analyse the molten steel flow in mould, a 2D model including mould and SENwas established. The fluctuation of on meniscus velocity field nozzle were analyzed. calculation results show that: (1) mouldwas highest area. When liquid flows out SEN, its decreases gradually. (2) There three regions mould. two reflux areas outside nozzle, dividing line is free surface, other area 0...
