A Newton–Cotes quadrature approach for solving the aerosol coagulation equation

This paper presents a direct approach to solving the aerosol coagulation equation. Newton–Cotes formulas are used to discretize the integral terms, and the semi-discrete system is built using collocation. A semi-implicit Gauss–Seidel time integration method is employed. The approach generalizes the semi-implicit method of Jacobson and is more accurate.
