摘要
在考察多个旋流水口技术的水模型试验中,制造加工传统单体浸入式水口的数量会随着试验条件数量的增加而增多,这会耗费大量的加工时间和成本。根据目前已有的旋流水口技术,文章提出一种全新的分体式旋流水口,将单体水口分为上、中、下三段,水口相邻两段采用螺纹旋拧的方式相互连接。水口上段保留传统水口特征;水口中段安装一个可拆卸的旋流转子;水口下段可选用直筒型或切向水口。这种分体水口结构不仅组装操作简单,降低了加工时间和成本,还有助于考察各旋流水口技术单独或耦合作用时的结晶器流场特征。
In the water modelling test for investigating the multiple swirling flow nozzle technologies,the number of the traditional submerged entry nozzle increases when increasing the number of experimental conditions,consuming a high amount of processing time and costs.Based on the existing swirling flow nozzle technologies,this paper proposes a novel split structure of swirling flow nozzle,which divides an entire nozzle into three parts and the adjacent two parts are connected by screwing.The upper part maintains the original characteristics.The middle part can be applied with or without a detachable swirling flow rotor.The lower part can be manufactured into a straight tube structure or a nozzle with tangential outlets.The assembly operation of this split nozzle is simple and fast.The flow field of the mold can be investigated when the independent or coupled swirl flow nozzle technologies are applied with this nozzle structure.
