Besides all the above-mentioned FF parameters, the CBD diameter (dCBD) and its density (ρCBD) account for effective parameters that are used for further optimization of the models and the physicochemical evaluation of the slurry simulation. To optimize the FFs, the Bayesian optimization was conducted according to the reference until achieving results sufficiently close to the experiments, then it was improved by systemic manual fitting for each of the FFs. To address the parameterization correctly, the viscosity of the slurry is measured experimentally as a function of γ̇ as demonstrated in Figure .
