Numerical Analysis of Heat Transfer in a Modular Biomass Reactor: CFD-Based Validation and Two-State Feedback Control Modeling
Short Introductive summary
Achieving thermal uniformity within laboratory-scale reactors remains a critical challenge, as it directly affects the reproducibility of experimental results and the quality of derived kinetic data. This study presents the development and validation of a Computational Fluid Dynamics (CFD) model for a modular bench-scale reactor, implemented in COMSOL Multiphysics® to simulate coupled heat transfer by conduction, convection, and radiation. Overall, the proposed Power-Based Thermal Model provides a non-intrusive and reliable digital tool for guiding structural design, improving process homogeneity, and accelerating optimization of thermochemical systems. This work demonstrates the value of CFD modeling as a decision-making framework for enhancing reactor performance and supporting digitalization in biomass pre-treatment research.
