(192e) Towards a General Framework for Development of CFD-Based Reduced-Order Compartment Models (Invited Talk)

While computational fluid dynamics (CFD)-based compartment models have become popular as a cost-effective alternative to full CFD modeling of complex mixing systems, developing these models requires substantial trial-and-error efforts. This study introduces a generalized zoning framework that facilitates the streamlined development of CFD-based compartment models, offering detailed characterization of the reduced-order representation of flow physics. By using a stirred tank as an illustrative example, a reduced-order model for species transport and heat transfer with turbulent flow is derived. Subsequently, the generalized zoning framework is presented to illustrate how a simplified CFD simulation can be used to construct a reduced-order compartment model. To evaluate the CFD-based compartment model, a test case involving the mixing of two miscible thermal fluids is conducted. The results demonstrate that the proposed zoning framework exhibits an accurate representation of the CFD simulation of hydrodynamics and demonstrates capabilities of capturing species and heat transfer in turbulent flow systems with complex geometric configurations.
