Abstract (EN): High-intensity paper drying processes involve the complex phenomena of multiphase transport in porous media. Impulse drying is such a process, in which enhanced liquid water removal is the key to energy savings. This paper concerns the study of the mechanical behavior of felts used in the papermaking industry, namely those applied in the press section of the paper machine. Here, a viscoelastoplastic model based on the cellular solids theory is presented, and its range of adequacy explored using data from uniaxial laboratory experiments. The model predictions show some agreement with the experiments but accurate documentation of multiphase-flow parameters and a proper heat and mass transport model, able to describe the multiphase transport in the course of the pressing event, would certainly improve the performance of the model.
