  1. 1. A physical modeling study of top blowing with focus on the penetration region

    University dissertation from Stockholm : KTH

    Author : Annie Nordquist; KTH.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; physical modelling; top blown converters; lances; blowing; penetration; swirl; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : This thesis work aimed at increasing the knowledge regarding phenomena occurring when gas is injected using a top-blown lance on to a bath. All results are based on physical modeling studies carried out both using low and high gas flow rates and nozzle diameters ranging from 0.8 mm to 3.0 mm. READ MORE

  2. 2. Concrete Structures Subjected to Fragment Impacts

    University dissertation from Stockholm : KTH

    Author : Joosef Leppänen; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; perforation; penetration; strain rate; scabbing; dynamic loading; fragment and projectile impacts; numerical simulations; spalling; concrete; blast wave;

    Abstract : As concrete is commonly used for protective structures, how a blast wave and fragment impacts from an explosion affect the concrete is an important issue. Concrete subjected to explosive loading responds very differently from statically loaded structures. READ MORE

  3. 3. Moisture Transport in Porous Media. Modelling Based on Kirchhoff Potentials

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Jesper Arfvidsson; Lund University.; Lunds universitet.; [1998]
    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 : The work presented in this thesis is focused on the development of the new concept to describe isothermal moisture transport using Kirchhoff potentials. The first four papers deal with moisture transport in porous media using Kirchhoff potentials. The last three papers deal with wood. READ MORE

  4. 4. A study of some aspects of gas-slag-metal interactions Towards dynamic process model and control

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Mattias Ek; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BOF; process modeling; phosphorous capacity; penetration depth; slag foaming; mixing time; inclusion removal;

    Abstract : The present thesis deals with the development of a new type of dynamic model for metallurgical reactors. It also covers some of the theoretical aspects of steelmaking that is necessary to include in such an application. The thesis consists of modeling work, high temperature experiments and cold model experiments. READ MORE

  5. 5. Corrosion of steel in concrete

    University dissertation from Swedish Cement and Concrete Research Institute, Stockholm

    Author : Kyösti Tuutti; [1982]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Corrosion; carbonation; chloride penetration; threshold values; free and bound chloride; acceptable depth of corrosion; corrosion products; environment types; cracks; cement type; service life calculations; test methods; korrosion; betong; betongkonstruktioner; armeringskorrosion; kloridinträngning; sprickor; livslängdsberäkningar;

    Abstract : The research work that is presented in this thesis aims at mapping out the various mechanisms which control the process of steel corrosion in concrete. The process of corrosion is illustrated with a schematic model where the service life is divided into a period of initiation and a period of propagation. READ MORE
