    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture distribtion; wood drying; wood; diffusion coefficient; numerical modelling; moisture flow; Moisture; transient measurements; periodic boundary condition; penetration depth; sorption coefficient; non-linear moisture flow; calculation model; anisitropy; Kirchhoff potentials; evaluation; moisture transport; Building construction; Byggnadsteknik;

    Abstract : Popular Abstract in Swedish Avhandlingen innehåller sju artiklar. Här presenteras ett nytt koncept för att beskriva hur fukt transporteras i porösa material. Detta bygger på införandet av en äkta flödespotential, Kirchhoff's potential. READ MORE

  2. 2. Rapid measurements of the moisture content in biofuel

    University dissertation from Institutionen för Samhällsteknik

    Author : Jenny Nyström; Mälardalens högskola.; [2006]
    Keywords : radiofrequency measurement; moisture content measurement; fuel characterization; biofuel; time domain measurement; Bulk measurement; Multivariate data analysis;

    Abstract : An increasing number of power plants in Scandinavia are beginning to use biofuel instead of coal or oil. The material in the new fuel is a mixture of woodchips, mostly Pine, Spruce and Salix, bark, GROT (tops and branches from felling waste) and sawdust from sawmills. It is heterogeneous, having a moisture content varying from 15% up to 65%. READ MORE

  4. 4. Moisture Conditions in Exterior Wooden Walls and Timber During Production and Use

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Lars Olsson; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory test; MRD-index; moisture; driving rain; hysteresis; wood; precipitation; timber; weather barrier; mould growth; façade; wall; wind barrier; measurement; field test; mold;

    Abstract : Thermal insulation of building envelopes has improved over the years. This means that building envelope have become more susceptible to defects, with an increased risk of moisture damage. The criteria for energy consumption have become more rigorous, but the shift should not lead to moisture problems. READ MORE

  5. 5. Moisture content profiles and surface phenomena during drying of wood

    University dissertation from Stockholm : Byggvetenskap

    Author : Anders Rosenkilde; KTH.; [2002]
    Keywords : computer tomography; diffusion; magnetic resonance; moisture measurement; moisture profiles; surface emission; wood drying;

    Abstract : Timber drying is one of the most important processes whenmanufacturing sawn timber products. The drying processinfluences deformations, surface checking, discoloration andhence, the product quality and the manufacturing costs. READ MORE
