Refining semi-analytical solutions for nonlinear aggregation and coupled aggregation-breakage population balance equations.
Abstract
Population balance models are crucial in various fields like aerosol physics, chemical engineering, and pharmaceutical sciences. This study focuses on refining semi-analytical solutions for nonlinear aggregation and coupled aggregation-breakage equations using the homotopy analysis method (HAM). The research aims to expedite convergence towards precise values by decomposing the non-linear operator. Various numerical methods have been used to solve these complex models, but limitations exist due to non-physical assumptions. The accelerated homotopy analysis method (AHAM) is introduced as an adaptable and efficient approach for solving these equations. The study includes a comparative analysis with existing methods and provides error estimates for the proposed methodology.
