Modeling a multiple-zone aIr impingement dryer

A complete model for the simulation of the drying process of a binary system in a modular air impingement dryer is presented. The underlying equations and the numerical scheme were chosen such that large-scale parameter studies could be performed efficiently with an ordinary Pc. The influence of the operating parameters on the drying progress and the energy efficiency was investigated, considering a wide range of technically important constraints such as proper web handling, the risk of explosion or the generation of bubbles in the coating
