Alternative reducing agents (ARAs) injected into the raceway zone of the blast furnace have diameters in the range of tens to thousands of micrometers. Larger ARA particles can develop significant internal temperature and species concentration gradients. These gradients determine the thermochemical ARA conversion characteristics. To capture these effects, a resolved Lagrangian particle model was developed, which solves mass and energy transport equations on a 1D grid. The influence of the resolved model on the conversion characteristics in the raceway zone is compared to classical unresolved or 0D Lagrangian models using computational fluid dynamics simulations in OpenFOAM ® .
注入高炉滚道区的替代还原剂（ARA）直径在几十到几千微米之间。较大的 ARA 颗粒会产生明显的内部温度和物种浓度梯度。这些梯度决定了 ARA 的热化学转化特性。为了捕捉这些影响，我们开发了一个解析拉格朗日粒子模型，在一维网格上求解质量和能量传输方程。利用 OpenFOAM ® 中的计算流体动力学模拟，比较了解析模型与经典的非解析或 0D 拉格朗日模型对流道区转化特性的影响。

Parametric studies were performed in a 1:2 scaled, curved water model using shadowgraphy to estimate bubble sizes for different casting parameters such as gas flow rate, liquid flow rate and mold width. Bubble diameter calculations were based on a machine learning algorithm using ImageJ software. Bubble diameters were correlated with input parameters using a deep-learning algorithm. The model performance was determined based on the coefficient of determination (R 2 ). The model showed significant promise with bootstrapping aggregation, validated with five-fold cross-validation and improved accuracy.
