Abstract

Sequential steps for unit process research based on numerical approaches to resource recycling were introduced along with examples. When designing unit processes through physics-based simulation, appropriate numerical methods and models must be identified. Using validated numerical models, values of model parameters and variables that are difficult to determine theoretically and experimentally can be computationally derived. Based on an understanding of the mechanism from a microscopic perspective, equipment performance can be predicted from a mesoscopic and macroscopic perspective. Overall numerical analysis is expanded to enhance the design of devices with improved performance through coupling with 3D modelling of equipment. It is expected that physics-based dynamic simulation will facilitate efficient and robust research in the field of resources recycling.

수치해석에 기반하여 자원순환 분야에서의 단위 공정 연구를 수행할 때 순차적으로 고려해야할 단계를 사례와 함께 제시하였다. 물리 기반 시뮬레이션을 통해 단위 공정을 설계함에 있어 수치해석기법을 결정하고 적절한 수치모델식을 개발 및 적용하는 것은 기본이 된다. 수치모델을 기반으로 하여 이론적·실험적으로 결정하기 난해한 변인을 전산적으로 도출하고 단위 공정 모사 시 세부 인자로 적용함으로써 단위 공정 해석을 강화할 수 있다. 미시적 관점에서의 공정 메커니즘 이해를 바탕으로 한 중시적·거시적 관점에서의 장비 성능 예측은 단위 공정 내에서의 공정 변수 파악 및 그에 따른 영향을 예측 가능하게 한다. 최종적으로 장비의 3차원 모델링과 연계함으로써 향상된 성능의 장비 디자인을 설계 가능하다. 이렇듯 수치해석 기반 시뮬레이션을 단위 공정 설계 이전의 사전 성능 검증 및 오류 검토 과정에 활용함으로써 효율적이고 탄탄한 연구가 수행가능할 것으로 기대한다.
