Three-dimension Mathematical Model Study on Fluid Flow in Thin Slab Continuous Caster Mold
-
摘要: 針對薄板坯連鑄結晶器中鋼液的紊流流動特征,利用商業軟件CFX4.2,建立了一個三維有限差分模型,計算這一限定空間射流的紊流時均場,并采用均相流模型,模擬了結晶器內鋼液液面形狀及速度場.通過計算,分析了浸入式水口形狀、拉速等工藝參數對薄板坯連鑄結晶器流場的影響,同時,研究了結晶器出口處速度分布對結晶器內鋼液流動的影響.Abstract: By using the commercial code CFX, the three-dimensional finite-difference model to sdriulate the fiuid flow in thin slab continuous caster mold has been set up. By using this model, the effects of the SEN variables and casting speed on sdrice turbulence and velocity fields in the thin slab mould are studied. The effect of the velocity distribution of noede outlet on the flow fiuid in the mould is also studied.
