Analysis is performed for fluid–structure interaction (FSI) by nozzle clogging in the continuous steel casting process. The scope of the analysis is confined to a submerged entry nozzle (SEN) interacting with turbulent molten steel flow. The fluid and solid domains are discretized in a single framework of the finite volume method in the OpenFOAM‐Extend version. Flow displacement by the clog is tracked and modal analysis performed to predict the vibration frequencies due to clogging. Parametric study is performed with respect to casting speed and immersed depth in the mold without clogging and with respect to the clog mass and its distribution on inner wall, bottom wall, and exit in the SEN. Results show the dominant frequency primarily influenced by the total mass of clog and not much affected by the clogging locations with good agreement between measurement and simulation.

连铸过程中流固耦合的喷嘴堵塞预测

在连续铸钢过程中，通过喷嘴堵塞对流体-结构相互作用（FSI）进行了分析。分析的范围仅限于与湍流的钢水流相互作用的浸入式水口（SEN）。在OpenFOAM-Extend版本的有限体积方法的单个框架中离散了流体域和固体域。跟踪由木log引起的流动位移，并进行模态分析以预测由于堵塞而引起的振动频率。针对铸造速度和模具中的浸入深度（无堵塞）以及堵塞物质量及其在SEN内壁，底壁和出口的分布进行参数研究。
