For understanding the energy use during vacuum dewatering and through air drying process, air flow through highly complex structure of paper has been investigated. Experiments were performed for a wide range of pressure drops and basis weights. In addition the pulp samples are refined to three different beating degrees. The calculated Reynolds numbers, based on the fiber diameter, varies in a wide range between 0.0002 and 80. The majority of data at low Reynolds number (below approximately 0.2) agree rather well with Darcy‟s law, so that the air flow is proportional to the pressure drop and inversely proportional to the grammage. However, the data at high Reynolds number obtained from air flow experiments using vacuum dewatering equipment, ...
