  1. 6. Modeling and optimisation of a rotary kiln reactor for the processing of battery materials

    Master-uppsats, KTH/Kemiteknik

    Författare :Danial Khawaja; [2021]
    Nyckelord :Granular flow; rolling mode; suspension model; two-fluid model; multiphase flow; Granulärt flöde; rullningsläge; suspensions modell; tvåvätskemodell; flerfasmodell;

    Sammanfattning : Roterugnar är cylindriska kärl som används för att höja materials temperaturer i en kontinuerlig process som kallas för kalcinering. Roterugnar kan tillämpas i olika processer såsom reduktion av oxidmalm samt återvinning av farligt avfall. LÄS MER

  3. 7. An Initial Analysis of Slurry Transportation in Subarctic Environment

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Wilhelm Friberg; [2021]
    Nyckelord :Slurry Transport;

    Sammanfattning : In today’s economy, it is important to have a sustainable business model where as little as possible goes to waste or finding solutions to create something useful out of by-products. Therefore, LKAB are looking to make a large investment into creating an infrastructure of several plants to turn tailings from the production of iron ore into usable products for several industries which LKAB has designated project ReeMAP (Rear Earth Elements and MonoAmmonium Phosphate).

  4. 8. Numerical Study on Air Demand of Free Surface Flows in a Discharge Tunnel

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Jonathan Barassa; Rickard Nordlöf; [2020]
    Nyckelord :Computational Fluid mechanics; Hydropower; Air demand; Free surface flows; ANSYS Fluent;

    Sammanfattning : Aeration issued through a ventilation shaft is an important measure to prevent cavitation and large gauge pressure in flood discharge tunnels. In order to dimension the ventilation shaft appropriately, itis necessary to have a good understanding of the air-water flow in the tunnel. LÄS MER

  5. 9. CFD Simulation of Particles in Pipe Flow and Mixing Tank

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Aljaz Janic; [2020]
    Nyckelord :Multiphase flow; particles; TetraPak; mixing tank; pipe flow;

    Sammanfattning : This project aimed to investigate the capability of the STAR CCM+ software when predicting the flow with particles using Lagrangian Particle Tracking and Discrete Element Method. The first part pertained to rectangular channel flow, with ratio between height of the channel and particle diameter (2h/Dp ) of 15. LÄS MER

  7. 10. CFD Simulations of Flow Characteristics of a Piano Key Weir Spillway

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära
