Abstract
This work numerically investigates the transport characteristics associated with the drying process of paper in the presence of a phase change material (PCM). The presence of PCM is studied in two different configurations: a layer of PCM embedded in the middle of paper and the PCM particles dispersed uniformly within the paper. This unique concept offers a new approach to paper drying by utilizing the latent-heat of fusion associated with the PCM, favorably impacting the energy efficiency of the drying process. The results indicate that the PCM acts as a heat source and a heat sink throughout the drying process, enhancing the drying rate. This study also includes the presence of an infrared emitter within the drying process. The corresponding absorption coefficient of PCM is measured experimentally. This paper is not concerned with the impact of presence of PCM on paper sheet properties.The proposed operating conditions and configuration presented here are solely for the purpose of illustration of the concept of drying in the presence of PCM.
