Aiming at the medium thickness slab caster in anshan isco, numerical simulations concerning fluid flow and free surface wave process of liquid steel in mold were conducted by using the cfx4. 4, a commercial software package for fluid flow analysis, in which the metallurgical functions of a submerged nozzle, specially the submerged nozzle with three holes, were investigated emphatically
摘要以鞍鋼中薄板坯連鑄機為對象，在商業軟體cfx4 . 4的平臺上對結晶器內鋼水流動和液面波動過程進行了數值模擬，重點研究了其所獨有的3孔浸入式水口的冶金功能。 -
The ratio of mach number between lateral jet and free flow induce intensity degree of jet interaction. it has no obvious difference between two interactions with two types of nozzle exit configuration, rectangle and ellipse. the shock in front of jet results in increase of shock resistance and the jet ejection causes increase of base resistance
研究表明，側噴流與來流馬赫數之比是影響繞流場的重要因素，該值越大則側噴干擾越強烈，矩形和橢圓形兩種側噴口形狀對側噴流場干擾波系的影響並不明顯。 -
The flow field of fadw is very complicated, especially in the free vortex jet zone. so the method is according to the ideal flow, including the design of the asymmetric supersonic laval nozzle and the diffuser
所以，本文所建立的fadw的基本設計方法是理想狀態下的設計方法，其中主要包括非對稱超音速噴管的設計和氣動窗口擴壓器的設計方法。
