Herein, the immersion process of a ceramic foam filter in a steel melt is investigated by means of numerical simulations, which are mainly based on the volume of fluid approach. The geometry of the used filters is modeled using an artificially generated beam model, which is convolved with a Gaussian kernel. The modeling approach enables the generation of filter geometries with, e.g., pore density and strut thickness similar to real ceramic foam filters. The main scope of the article is to show the effect of the immersion velocity of the filter on the formation of gas bubbles inside the pore cavities of the ceramic filter. Moreover, the influence of the contact angle on the volume fraction of gas bubbles, which remain in the filter, is investigated. For better understanding, the numerical results are underlined using 3D visualization and virtual reality.

泡沫陶瓷过滤器在钢熔体中浸泡过程的数值评估

本文通过数值模拟研究了泡沫陶瓷过滤器在钢液中的浸没过程，数值模拟主要基于流体体积的方法。所用滤波器的几何形状使用人工生成的光束模型建模，该光束模型与高斯核卷积。建模方法能够生成过滤器几何形状，例如，与真实陶瓷泡沫过滤器相似的孔密度和支柱厚度。本文的主要范围是展示过滤器的浸没速度对陶瓷过滤器孔腔内气泡形成的影响。此外，还研究了接触角对残留在过滤器中的气泡体积分数的影响。为了更好的理解，
