  1. 1. Mass transfer and slag-metal reaction in ladle refining a CFD approach

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Eva Ramström; KTH.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reoxidation; desulphurisation; CFD; ladle treatment; model; TECHNOLOGY Materials science Other materials science; TEKNIKVETENSKAP Teknisk materialvetenskap Övrig teknisk materialvetenskap;

    Sammanfattning :  In order to optimise the ladle treatment mass transfer modelling of aluminium addition and homogenisation time was carried out. It was stressed that incorporating slag-metal reactions into the mass transfer modelling strongly would enhance the reliability and amount of information to be analyzed from the CFD calculations.

    Sammanfattning : The thermal indoor climate is a complicated combination of a number of physical variables, all of which strongly affect people’s well-being. The indoor climate not only heavily affects people’s health and life quality, but also their productivity and ability to work efficiently. LÄS MER

  3. 3. CFD Methods for Predicting Aircraft Scaling Effects

    Detta är en avhandling från Stockholm : KTH

    Författare :Karl Pettersson; KTH.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Scaling Effects; Boundary Layer Transition; Preconditioning; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Sammanfattning : This thesis deals with the problems of scaling aerodynamic data from wind tunnel to free flight  conditions. The main challenges when this scaling should be performed is how the model support, wall interference and the potentially lower Reynolds number in the windtunnel should be corrected. LÄS MER

  5. 5. Drying of iron ore pellets analysis with CFD

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Anna-Lena Ljung; Luleå tekniska universitet.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Iron ore pellets are a highly refined product and for companies such as LKAB it is important to constantly improve the pelletization in order to enhance production and improve product quality. A long term goal has been established to develop and considerably refine tools and techniques with which the drying zone of a pelletizing plant can be optimized. LÄS MER
