ABSTRACT
Two-dimensionalnumerical simulations usingfinite volume method and an interface capturingschemeare usedto predict the shape of free surfacewave that is created in a mold due to the flow fromsubmergedentry nozzle. In the present work,instead of steel and argon, water and air enter intothe mold. It has been observed that the free surfaceis wavy in nature. Three differentsubmerged entrynozzle(SEN)models were taken for numericalanalysis.Contribution of water velocity,differentport to Bore ratio (P/B), size of upper recirculationroll on free surface were investigated for designinga submerged entry nozzle. Itwas observed that Pent-Roof type nozzleis a betteroneas it shows lesserfluctuation.
