A novel method for precise determination of maximum particle loading fraction in highly concentrated suspensions
Hypothesis
Accurately predicting the maximum particle loading fraction (ϕmax) of a suspension remains a significant challenge in both theoretical modeling and industrial applications.
Experiments
We present a novel method that surpasses existing approaches by precisely determining ϕmax through predicting the general suspension viscosity at a constant shear rate as a function of particle volume fraction. Our approach leverages boundary and initial conditions to pinpoint ϕmax with precision.
Findings
The proposed model flawlessly captures viscosity behavior across the entire range of volume fractions without pre-assumptions or limitations, showcasing its remarkable versatility. We validate the efficacy of our method by comparing its predictions with established theoretical models and diverse experimental data for various suspensions, including nanofluids and yield stress fluids, as reported in the literature. This extends to the evaluation of crucial parameters related to ϕmax within existing suspension viscosity models. Beyond its immediate applications, this approach opens avenues for exploring relationships between ϕmax and other suspension properties, potentially leading to broader advancements in understanding or manipulating suspension rheological behavior in material science.
