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

    Author : Eva Ramström; Du Sichen; Mselly Nozotta; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reoxidation; desulphurisation; CFD; ladle treatment; model; Other materials science; Övrig teknisk materialvetenskap;

    Abstract :   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.

  4. 2. A Model for Simulation of Fiber Suspension Flows

    Author : David Hammarström; KTH; []
    Keywords : rheology; fiber; suspension; CFD; model; wall; slip; turbulence;

    Abstract : The fiber suspensions in the production line from wood topaper are subjected to many types of chemical and mechanicalprocesses, in which the flow of the suspension is of vitalimportance. The flow of the suspension determines the degree ofuniformity of the fibers through the processing, which inreturn affects the properties of the fiber suspension. READ MORE

  5. 3. Numerical simulation and analysis of multi-scale cavitating flows using a hybrid mixture-bubble model

    Author : Ebrahim Ghahramani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Homogeneous mixture model; Lagrangian bubble model; CFD; Cavitation; OpenFOAM; Multiphase flow; Hybrid model; Multi-scale;

    Abstract : The aim of this research is to model and analyse multi-scale cavitating flows with a certain emphasis on small sub-grid vapour structures. Cavitating flows include vapour structures with different length scales, from micro-bubbles to large cavities. READ MORE

  6. 4. Vertical Display Cabinets in Supermarkets - Energy Efficiency and the Influence of Air Flows

    Author : Monica Axell; RISE; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; display cabinet; model; simulation; supermarket; CFD; air curtain; energy; performance; air distribution; display case; infiltration;

    Abstract : This thesis concerns investigations of the performance of vertical refrigerated display cabinets. Such cabinets are in widespread use and account for a considerable proportion of the energy used in shops. The open front is important for the shop-owner, who wants the chilled items in the cabinet to be well exposed and easily accessible. READ MORE

  7. 5. The Aerodynamic Correlation of a Scale Model with a Full Size Car

    Author : Lasse Malmkjaer Christoffersen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooling flow.; Correlation; Experiment; Reynolds number; Road Vehicle Aerodynamics; CFD; Scale model;

    Abstract : Reducing the Worlds consumption of energy has become an important part of the current political and environmental debate. The reasons are obvious: World population is increasing, continued growth in living standards, finite availability of resources and finally green house gas emissions from energy production have to be brought down to stabilize temperatures.
