  1. 1. Petrological, geochemical and structural evidence of fluid-rock interaction in the Siljan Ring

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : William Crang; [2024]
    Keywords : methane; hydrothermal fluids; fluid-rock interaction; impact craters; reduction haloes; pyrite preservation; Siljan Ring;

    Abstract : The Siljan Ring in Dalarna, Sweden is the site of the largest meteor impact crater in Europe and has long been a topic of discussion regarding methane production. However, the source of this methane and the timing of production in relation to the impact remain unclear. READ MORE

  2. 2. CFD investigation of a unit cell inside a Plate Heat Exchanger

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Mattias Ly; [2023]
    Keywords : Plate Heat Exchanger; CFD; Computational Fluid Dynamics; LES; Large Eddy Simulation; Periodic; Unit Cell; Technology and Engineering;

    Abstract : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. READ MORE

  3. 3. Design and Modelling of a Container for Optimal Flow Rate and Wastewater Purification

    University essay from Umeå universitet/Institutionen för fysik

    Author : Olle Stenlund; [2021]
    Keywords : CFD Simulation; Design; Construction; Pumping System; Water purification;

    Abstract :   Industries are becoming more aware of how they use water in their production process. In many cases, they release wastewater back into the water supply untreated, which can cause adverse side effects to the ecosystem. A sustainable environment requires efficient water purification. One approach to purify wastewater uses rotating bed reactors. READ MORE

  4. 4. Simulated cerebrospinal fluid motion due to pulsatile arterial flow : Master Thesis Project

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jesper Hägglund; [2021]
    Keywords : Computational fluid dynamics; Fluid structure interaction; Pulsatile flow;

    Abstract : All organs, including the brain, need a pathway to remove neurotoxic extracellular proteins. In the brain this is called the glymphatic system. The glymphatic system works by exchanging proteins from interstitial fluids to cerebrospinal fluids. The extracellular proteins are then removed through the cerebrospinal fluid drains. READ MORE

  5. 5. Extensional Instability in Complex Fluids: A Computational Study

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Muhammed Abdulrazaq; [2020]
    Keywords : Complex Fluids; Computational Rheology; Elastoviscoplastic Fluids; Instability.; Komplexa vätskor; Beräkningsreologi; Elastoviskoplastiska vätskor; Instabilitet.;

    Abstract : In this study, instability and failure in complex fluids (Elastoviscoplastic fluids) is explored using the classic Considère (F˙ < 0) and stress curvature (σ¨ < 0) criteria. Employing the Saramito model, numerical simulation of the extensional protocol on non-Newtonian fluids is carried out. READ MORE
