  1. 1. Influence of ventilation on ro-ro space fire development : A study using two-zone fire models in order to explore tendencies of how different ventilation parameters affects the fire development in a ro-ro space

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser; Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Martin Lindgren; Andreas Lilja; [2019]
    Keywords : Fire; Ro-ro space; Ventilation; Simulation; Two-zone model; Brand; Rorolastutrymme; Ventilation; Simulering; Tvåzonsmodell;

    Abstract : A ship to which vehicles and other loads can be rolled on and off is usually named ro-ro ship. A ro-ro ship consists of large corridor shaped space, normally extending to a considerable length or the entire length of the ship, which is usually loaded with various vehicles or stowage units.

  2. 2. A Study of Various Parameters Affecting Adhesion of Coatings to Metal Substrates

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Worabhorn Pathanatecha; [2019]
    Keywords : adhesion; coatings; metal substrates; silanes; polyurethanes; surface energy; crosslinking agent; adhesion promoters; vidhäftning; beläggningar; metallunderlag; silaner; polyuretaner; ytenergi; tvärbindningsmedel; vidhäftningspromotor;

    Abstract : The adhesion of coatings is of high importance in the coating industry and a more thorough understanding of adhesion behavior is required. In this thesis work, seven parameters affecting adhesion of silane-modified poly(urethane urea) (PUSi) coatings on pretreated steel and aluminum substrates were studied. READ MORE

  3. 3. Finite Element Modelling and Parametric Studies of Semi-Closed Thin-Walled Steel Polygonal Columns - Application on Steel Lattice Towers for Wind Turbines

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Bona Ryan; [2017]
    Keywords : Lattice tower; Thin-walled element; Semi-closed polygonal section; Finite element analysis; Parametric study; Buckling; Python script; Matlab script; Eurocode 3; Factorial design;

    Abstract : The trend of structural engineering in the recent years is toward the use of lighter and moreeconomical structural elements. In steel construction, peculiarly, thin-walled structural elements arebecoming more popular and have a growing importance. READ MORE

  4. 4. Possible reasons for flaking appearance during cold rolling on an austenitic stainless steel

    University essay from KTH/Materialvetenskap; KTH/Materialvetenskap

    Author : Kristina Åkerlind; Zenja Jefimova; [2016]
    Keywords : Flaking; Austenitic stainless steel; Cold rolling; Oxide scale;

    Abstract : The research describes possible reasons why the flaking tendency during cold rolling can vary between different austenitic stainless steels. The flaking phenomenon was observed after a rolling process in Granlund Tools AB’s roll reducing mill “KOR-8”. READ MORE

  5. 5. The Process Influence on Strength Properties of an Austenitic Stainless Steel (254 SMO)

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Anna Hellqvist; [2014]
    Keywords : stainless steel; hot rolling; levelling; strength; material properties; process parameters;

    Abstract : This work has been performed at Outokumpu Stainless AB, QPE, in Degerfors where focus is on production of hot rolled tailor-made quarto plate in special stainless steel grades such as highly alloyed austenitics and duplex steel grades. After a period with low values in strength and a lot of deviations in tensile tests for the highly alloyed austenitic stainless steel, 254 SMO, there was a need to investigate what influence some parameters during process has on strength values.
