本文介绍了为描述中间包中钢水主动流动的流体动力学而进行的计算机模拟和实验室实验的结果。描述 FCD 对中间包操作的正确影响的参数之一是对活动流动区（分散的活塞流和充分混合的体积流量）的描述。正在调查的设施是一个单水口中间包，设计用于铸造连铸板坯。使用商业程序 Ansys-Fluent 对钢水流动进行计算机模拟。为了验证数值模型并验证从计算机模拟获得的所检查的中间包设备变体中出现的流体动力条件，采用了中间包的物理模型。在模拟钢流过中间包过程的实验室测试中，记录了 E 型 RTD 曲线，然后将其与计算机模拟获得的结果进行对比。为了获得测试的中间包装置变体的完整流体动力学图，对等温和非等温条件进行了计算机模拟。
This paper presents the results of a computer simulation and laboratory experiments carried out to describe the hydrodynamics of steel active flow in the tundish. One of the parameters describing the correct influence of FCDs on the tundish operation is the description of the active flow zone (dispersed plug flow and well mixed volume flow). The facility under investigation is a single-nozzle tundish designed for casting concast slabs. Computer simulations of liquid steel flow were performed using the commercial program Ansys-Fluent. For the validation of the numerical model and verification of the hydrodynamic conditions occurring in the examined tundish furniture variants, obtained from the computer simulations, a physical model of the tundish was employed. During laboratory tests simulating the process of steel flowing through the tundish, E type RTD curves were recorded, which were then juxtaposed with results obtained from computer simulations. In order to obtain a complete hydrodynamic picture in the tundish furniture variants tested, the computer simulations were performed for both isothermal and non-isothermal conditions.
