A new droplet drying model incorporating a population balance to model suspended solids is introduced. The population is evolved using a moment method with an interpolative closure employed in the case of a size dependent solids diffusion coefficient. This paper demonstrates the formulation and discusses the benefits of the new model, before presenting simulations of droplets containing colloidal silica and sodium sulphate. The results are compared with experimental data from the literature in the regime prior to shell formation. (C) 2008 Elsevier Ltd. All rights reserved.
