摘要使用水力学模型和数学模型硏究了旋转水II结晶器内流场，分析了叶片角度和位置对结晶器内流场的爆 响。结果表明：旋流水口使结晶器内的流动均匀，出现上环流区：叶片角度的减小，旋转流股的冲击深度减小， 环流区上移，当叶片角度为60",出现下环流区：转子距水口出口的距离越大，旋转流股的冲击深度越大。 关键词 直通水口，旋流水口，冲击深度，环流区

Abstract: The water and matheinalical modeling was carried out to study the flow iield using swirling How nozzle in continuous casting billet mould, the influent of the angle and location of the blade on flow pattern inside the mould was analyzed. The results showed that the flow field in mould was uniformed and the upper circulation regions were observed with swirling flow nozzle; the penetration depth of swirling fluid was reduced and the upper circulating regions moved upward with the angle of the blade reduced, and the lower circulation regions were observed in the case of 60° blade angle; the penetration depth of swirling flow was increased with the distance increased between the blade and outlet. Keywords： straight nozzle; swirling flow nozzle; impact depth; circulation
