  1. 11. Mass and Heat Transport in Dryer Fabrics - Experiments and Modelling

    Författare :Simon Smrtnik; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat transport; dryer fabric design; fabric parameters; mass transport; condensation;

    Sammanfattning : A dryer fabric is used in the multi-cylinder dryer in order to improve the runnability of the web and to establish proper contact between the web and the hot cylinder, thus improving the heat transport. The dryer fabric separates the hot and moist paper from the ambient drying air and significantly influences the mass and heat transport. LÄS MER

  3. 12. High temperature corrosion of some selected stainless steels and Ni-base alloys – an advanced microscopy study

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxidation; KCl; STEM; high-temperature materials; STEM EDX; TKD.;

    Sammanfattning : The thesis deals with high temperature corrosion behavior of some selective stainless steels and Ni-base alloys with applications in power generation technologies, e.g. boilers fired by biomass and waste. LÄS MER

  4. 13. Impact of Weather on Air Traffic Control

    Författare :Anastasia Lemetti; Valentin Polishchuk; Tatiana Polishchuk; Junzi Sun; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Weather has a strong impact on Air Traffic Management (ATM). Inefficient weather avoidance procedures and inaccurate prognosis lead to longer aircraft routes and, as a result, to fuel waste and increased negative environmental impact. LÄS MER

  5. 14. Chloride Transport in Concrete under the Frost Action – An Experimental Study

    Författare :Bo Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature; chloride; concrete; freeze-thaw cycles; water uptake; chloride profile; frost action; transport;

    Sammanfattning : Frost-induced ingress of chloride in concrete is one of the typical transport phenomena of aggressive substances when structures expose to severe environments such as marine tidal zone and de-icing highway in winter seasons. It is well known that Chloride ingress in concrete causes the reinforcement corrosion. LÄS MER

  7. 15. Decision Models for the Procurement of Subsidised Air Services

    Författare :Alan Kinene; Tobias Andersson Granberg; Valentin Polishchuk; Clas Rydergren; Svein Bråthen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Small communities or remote regions are usually ignored by airlines because they have insufficient passenger demand and the air services to and from these regions are unprofitable. Free market conditions would lead to the lack of air connectivity to and from remote regions, hence transportation authorities intervene by procuring air services to guarantee improved accessibility for these regions.
