In the present article, a model combining the benefits of the small scale and large scale approaches towards modeling paper drying in a paper machine dryer section environment is described. The model is transient and two-dimensional, taking into account the MD and the thickness directions but neglecting the phenomena in the CD direction. The combined model consists of two parts: 1. A large scale CFD model of the surroundings of the paper web solving the RANS equations 2. A specific-purpose small scale model for heat and moisture transport phenomena inside the paper web. The model is aimed at predicting the drying process in a paper production environment. The present model can be combined with a separate paper web deflection model in order to simulate the drying process and the paper web runnability simultaneously.
