1. Creep, deformation and moisture redistribution during air convective wood drying and conditioning : air convective wood drying and conditioning
Sammanfattning : Air convective wood drying is associated with a considerable risk for damage to the timber, especially checking and warping. This thesis contains an analysis of creep and deformation during wood drying related to stress development and susceptibility of checking. Also heat and mass transfer problems in the wood drying process are considered. LÄS MER
2. Single Phase Convective Heat Transfer with Nanofluids : An Experimental Approach
Sammanfattning : Nanofluids (NFs) are engineered colloids of nanoparticles (NPs) dispersed homogenously within base fluids (BFs). Due to the presence of NPs, the thermophysical and transport properties of BFs are subject to change. LÄS MER
3. Heat Flow in Building Components, Experiment and Analysis
Sammanfattning : Three building components exposed to natural climate were studied: a dynamic insulation in the ceiling of a house, an outer wall and one window in the same wall. The term dynamic insulation implies that part of the inlet or exhaust air passes through the insulation of a house. LÄS MER
4. Modelling of Mass and Heat Transport in Paper - Evaluation of Mechanisms and Shrinkage
Sammanfattning : In this work a one-dimensional model for the mass and heat transport in the thickness direction of paper has been developed. Solid-based coordinates were applied to simplify incorporation of shrinkage. Liquid diffusion, gas convection and vapour and air diffusion were incorporated as mass transport mechansims. LÄS MER
5. Superheated Steam Drying of Wood Chips in Pneumatic Conveying Dryers
Sammanfattning : This thesis contains a fundamental investigation of a pneumatic conveying dryer. The model presented can be used both for design and rating purposes and, although the main emphasis is put on the drying of wood chips in superheated steam, the results can be used for other systems as well.
