  1. 21. Drying of iron ore pellets : analysis with CFD

    Författare :Anna-Lena Ljung; Luleå tekniska universitet; []
    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

  3. 22. Compression moulding of SMC : experiments and simulation

    Författare :Jimmy Olsson; Daniel Ståhlberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Due to excellent properties and relatively low material and manufacturing costs, the use of fibre reinforced polymer composites have increased during the last decades. One method that is suitable for large scale productions of e.g. lightweight vehicle components is compression moulding of sheet moulding compound (SMC). LÄS MER

  4. 23. Numerical modelling of swirling drying flow

    Författare :Simon Johansson; Per Carlsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Waste hydrochloric acid (HCl) from the pickling process at SSAB EMEA in Borl¨ange, Sweden, is regenerated using a technique called spray roasting where waste HCl is sprayed into a hot reactor through four spray nozzles at the top of the reactor. The regeneration (drying) process is driven by four natural gas burners placed symmetrically along the periphery of the reactor and causes the water in the waste acid droplets to evaporate. LÄS MER

  5. 24. Theoretical magnetohydrodynamic and solidification studies of continuous strip casting

    Författare :Hans B. Löfgren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : The continuous casting of steel strips has been under investigation and development for several decades. The aim of this development is to be able to cast steel strips in a thickness range from 1 to 10 mm. Today, there are basically two such methods: the single-belt caster and the twin-roll caster.

  7. 25. LES of Jets and Sprays Injected into Crossflow

    Författare :Mirko Salewski; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaser; fluid dynamics; large eddy simulation; spray; plasmas; Gases; lagrangian particle tracking; jet in crossflow; fluiddynamik; plasma;

    Sammanfattning : The objective of this thesis is to numerically simulate a fluid jet injected into a crossflow of the same or another fluid, respectively. Such flows are encountered in many engineering applications in which cooling or mixing plays an important role, e.g. gas turbine combustors. LÄS MER
