Abstract Summary (Max 250 words)
The modeling of solvent extraction processes using coupled Computational Fluid Dynamics (CFD) and Population Balance Modeling (PBM) represents a robust solution for industrial applications. In this context, the simplified zero-dimensional (0D) PBM informed by single-phase CFD simulations can significantly reduce computational cost while providing results well suited to a wide range of applications. This approach accounts for the full turbulent energy spectrum by computing the second-order longitudinal structure function [1]. The objective of this work is to evaluate the impact of the CFD strategies (spatial and mesh resolutions, rotation modeling strategies - namely the Multi Reference Frame (MRF) and Sliding Mesh (SM) methods - and turbulence modeling approaches (standard k–ε model and Detached Eddy Simulation (DES) coupled with the realizable k–ε model) on the breakage frequency, Γ , and the resulting Sauter mean diameter, d32, within the reduced PBM using the modified Coulaloglou and Tavlarides breakage kernel [2]. Moreover, we investigate the evolution of the Taylor microscale and the Integral macroscale for each CFD strategy, relying on the findings of Escudié and Wu [3,4]. The results highlighted the domains beyond which k/ε has converged, leading to a maximum deviation of 5 % on the d32 estimation between the converged simulations. 1.
