Abstract

A mathematical model for the computation of chemical equilibrium of atmospheric inorganic aerosols is proposed. The equilibrium is given by the minimum of the Gibbs free energy for a system involving an aqueous phase, a gas phase and solid salts. A primal-dual method solving the Karush-Kuhn-Tucker conditions is detailed. An active set/Newton method permits the computation of the minimum and track solid salts at the equilibrium.
