  2. 1. Coated Norway Spruce : Influence of Wood Characteristics on Water Sorption and Coating Durability

    Author : Tinh Sjökvist; Åsa Blom; Carsten Mai; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Heartwood; Sapwood; Wood extractives; Moisture content; Paint; Alkyd; Acrylic; Linseed oil; Calcimine paint; Mould; Fungi; Algae; Weathering; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Wood used outdoors is often degraded and discoloured by microorganisms as a natural part of its life cycle, particularly when exposed to high levels of moisture for prolonged times. In this case, the application of a coating (i.e. paint) is an option for increasing the service life of the wood. READ MORE

  4. 2. Moisture Balance in Painted Wood Panelling

    Author : Stefan Hjort; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture transport; numerical simulation; rot; wood; moisture conditions; paint;

    Abstract : Over the last years thousands of houses have been damaged by wood rot in the exterior wood panelling due to excessive moisture conditions. This thesis is about moisture conditions and the way moisture enters and exits painted wood panelling structures. READ MORE

  5. 3. Numerical and Experimental Investigation of Hydrodynamic Mechanisms in Erosive Sheet Cavitation

    Author : Mohammad Hossein Arabnejad Khanouki; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paint test; Numerical simulation; High speed visualization; Shedding behavior; Hydrodynamics mechanisms of cavitation erosion iii; Sheet cavitation;

    Abstract : Cavitation erosion is one of the limiting factors in the design of hydraulic machinery as it is associated with the reduction in the operating life-time of a hydraulic machine and a significant increase in maintenance cost. In order to be able to design a hydraulic machine with a low risk of cavitation erosion, understanding the hydrodynamic mechanisms controlling the cavitation erosion is of great importance.

  6. 4. Studies on the barrier properties of exterior wood coatings

    Author : Jan Ekstedt; KTH; []
    Keywords : Coatings; surfactants; water absorption value; EN 927; paint; additives; moisture dynamics; absorption; desorption; artificial weathering; artificial exposure; computerized tomography; MRI.;

    Abstract : Coatings for exterior wood have two basic functions. One isto give an aesthetically acceptable surface appearance andcolour. The other is to provide protection against wooddegradation by microbiological or physical attack. READ MORE

  7. 5. Measuring with pressure sensitive paint in time-varying flows

    Author : Markus Pastuhoff; Henrik Henrk Alfredsson; Ulrich Henne; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pressure sensitive paint; fluid mechanics; internal flow; pulsating flow;

    Abstract : Increasingly tougher legislation on internal combustion engine emissions drives the development towards smaller engines with higher efficiency where an important component is the gas-exchange system and especially the turbocharger. The flow in the gas-exchange system is inherently pulsating and unsteady and the present thesis aims at investigating if and how pressure sensitive paint (PSP) can be used for internal unsteady flows of relevance for engine applications.
