  1. 1. Numerical modelling for characterization of the granular flows impact on the gas flow in a packed-bed-reactor

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Anton Sundström; [2020]
    Keywords : DEM; Discrete element method;

    Abstract : The goal of the project was to characterize the granular flows impact on the gas flow in a packed-bed-reactor. The study was created at Swerim as a master's thesis for Luleå University of Technology. The packed-bed-reactor geometry used in this study is a scaled down blast furnace model. READ MORE

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

    University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutionen för fysik och astronomi

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

    Abstract : 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. READ MORE

  3. 3. Dimples in corrugated channels to improve efficiency in plate heat exchangers

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Gustav Karlsson; [2020]
    Keywords : Dimples; Plate Heat Exchangers; Heat Transfer Enhancement; CFD; Large Eddy Simulation; Reynolds Averaged Navier Stokes Simulation; chemical engineering; kemiteknik; Technology and Engineering;

    Abstract : The development of new heat exchanger patterns is ever changing. Companies are constantly pushing innovation to satisfy costumer needs in terms of thermal efficiency, reliability and serviceability. In this thesis, the implementation of dimples in the corrugated pattern of a plate heat exchanger is investigated to increase the thermal efficiency. READ MORE

  4. 4. CFD Simulations of Flow Characteristics of a Piano Key Weir Spillway

    University essay from Uppsala universitet/Elektricitetslära; Uppsala universitet/Elektricitetslära

    Author : William Sjösten; Victor Vadling; [2020]
    Keywords : Piano Key Weir; Ansys Fluent; Multiphase Flow; Spillway; Flow Characteristics; CFD; Realizable k-epsilon; Volume of Fluid; Renolds-averaged Navier-Stokes;

    Abstract : Comprehensive rehabilitation projects of dam spillways are made in Sweden, due to stricter dam safety guidelines for their discharge capacity. The Piano Key Weir (PKW) is an innovative design which has proven effective through several renovation projects made in many countries including France. READ MORE

  5. 5. Rock cavern as thermal energy storage

    University essay from Luleå tekniska universitet/Energivetenskap

    Author : Simon Berglund; [2020]
    Keywords : Rock cavern; Waste heat; District heating; Intermittent operation; Sustainability; Heat storage; Carbon dioxide reduction; Bergrum; Spillvärme; Fjärrvärme; Intermittent drift; Hållbarhet; Värmelagring; Koldioxid reducering;

    Abstract : In the fall of 2019, a comprehensive idea study was conducted on heat storage in two rock caverns located at Näsudden in Skelleftehamn and was part of the project course "Energiteknik, huvudkurs" at Luleå University of Technology. This idea study investigated the conditions of using waste heat from Boliden AB:s copper smeltery (Rönnskär) and storing this waste heat in two rock caverns and use them as seasonal thermal storage tanks, with the purpose of using the heat in the nearby district heating network, thus replacing some of the oil burned at Rönnskär.
