  2. 6. Studies on Building Air Leakage -a transient pressurisation method, measurements and modelling

    Author : Björn Mattsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air change rate; Airtightness; CFD-simulations; moisture transport; air leakage; mould growth; cold attics; transient pressurisation;

    Abstract : Airtightness of the building envelope is a key factor for good performance of a building. The main part of this thesis deals with the exploration of a transient pressurisation method for air leakage measurements.In the transient method, an enclosure is pressurised to a desired pressure. The air flow into the enclosure is then stopped. READ MORE

  4. 7. A Study of the Initial Mould Filling during Up-hill Ingot Casting

    Author : Line Hallgren; Pär Jönsson; Anders Tilliander; Seppo Louhenkilpi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swirling flow; up-hill teeming; nozzle; casting; fluid flow; modelling; CFD; LDA; swirl; ingot casting; filling; red eye;

    Abstract : The fluid flow in the mould during up-hill teeming is of great importance for the quality of the cast ingot and thereby the quality of the final steel products. At the early stage of the filling of an up-hill teeming mould, liquid steel flows with a high velocity from the runner into the mould. READ MORE

  5. 8. Development and Implementation of a Mouldable Soft Magnetic Composite

    Author : Leif Siesing; Industriell Produktion; []
    Keywords : Soft magnetic composite; Mouldable; Manufacturing; Powder; Thermal conductivity; Permeability; Magnetic loss; Finite element analysis;

    Abstract : Electrical machines, chokes and induction heaters are found in most homes,offices and factories all over the world. They are used to create movement, filtrate the power or to generate heat. A typical unit consist of a coil and a flux conductor material. READ MORE
