커튼 코팅 공정에서 자동격자생성 기법을 이용한 비정상 유동 해석을 위한 유한요소법 개발

In this study, the transient curtain coating process is computationally carried out via the in-house code developed using a finite element method(FEM). Incorporating sophisticated auto-remeshing techniques, our numerical implementaion for FEM not only captures the complex flow dynamics inherent in this curtain coating process but also adapts to the rapid deformations observed at important flow zones in the curtain coating flow. The stability and accuracy of the proposed computational model have been rigorously tested againsta spectrum of flow rates, viscosities, and substrate speeds, proving its robustness and reliability. As we continue our research, we aim to further enhance these simulation algorithms identifying optimal operating conditions that could be key in ensuring consistent qualityacross materials with different rheological properties in the curtain coating process.
