本文介绍了中间包内钢流的计算机模拟结果。在数值模拟过程中，采用了6种不同的湍流模型。在工作中，作者测试了：k-ε， RNG k-ε, Realizable k-ε, k-ω， RSM和DES湍流模型。采用其他形式的中间包内部空间设备对中间包碎片进行了研究。数值计算基于控制体积法，使用计算机程序Fluent。计算得到了钢的流动场、湍流强度场和停留时间场。对于所有湍流模型的平均停留时间，计算了停留时间和RTD曲线（E型和F型）的方差。
The article presents the results of computer simulations of steel flow in the tundish. During numerical simulation six different turbulence model were applied. At work authors tested: k-ε, RNG k-ε, Realizable k-ε, k-ω, RSM and DES turbulence models. To research fragment of tundish with other form of tundish internal space equipment was chosen. Numerical computations were based on the control volumes method, using the computer program Fluent. As a result of computations, fields of steel flow, turbulence intensity, residence time were obtained. For all turbulence models mean residence time, variance of the time of residence and RTD curves (type E and F) were calculated.
