  1. 21. 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. 22. Epidemiology and genotyping of Methicillin-resistant Staphylococcus aureus with amplicon-based Nanopore-sequencing : Creating a panel of clinically relevant genes

    University essay from Uppsala universitet/Institutionen för medicinsk cellbiologi

    Author : Max Koivistoinen Jonsson; [2023]
    Keywords : Amplicon-sequencing; Genomic typing; MRSA; MSSA; MinION;

    Abstract : Methicillin-resistant Staphylococcus aureus (MRSA) is a variant of the more common Methicillin-Susceptible Staphylococcus aureus (MSSA), an opportunistic pathogen a portion of the human population carries as normal bacterial flora. When an outbreak of MRSA occurs, it is often important to determine if and how these strains are related to each other. READ MORE

  4. 23. MODELLING OF HEAT TRANSFER OF RAILWAY SWITCH HEATING

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Siddharth Suresh Sumathi; [2023]
    Keywords : Conjugate Heat transfer analysis; transient analysis; CFD; insulation; measurement data uncertainties.; Konjugat Värmeöverföringsanalys; transientanalys; CFD; isolering; mätdata osäkerheter.;

    Abstract : Switches and crossings are vital components of the railway network. Obstacles to the smooth functioning of these components could result in delays and network traffic. Given the geographical location of Sweden, snow is one of the major obstacles for the switches. READ MORE

  5. 24. Numerical modeling of airflow on the cathode-side of a bipolar flow plate : How the formed geometry affects the pressure drop and flow distribution in a hydrogen fuel cell

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Olivia Johansson; [2023]
    Keywords : Performance; Cross-sectional geometry; Computational fluid dynamics;

    Abstract : Climate change and rising temperatures is a well-known problem. To tackle global warming a transition from fossil fuels to renewable and reliable energy sources is necessary. Hydrogen, in fuel cells, is proposed to replace diesel and gasoline in the transport sector. READ MORE

  6. 25. Simulation of Combustion in a Hybrid Rocket Engine

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Oscar Andersson; [2023]
    Keywords : Thesis; Hybrid Rocket Engine; CFD; computational fluid dynamics; combustion;

    Abstract : A numerical investigation on the combustion mechanics of a hybrid rocket engine is performed through unsteady Reynolds-averaged Navier-Stokes simulation. The hybrid rocket engine model is based on an experimental laboratory scale engine design operating on GOX and HDPE as a propellant. READ MORE
