  1. 1. Solving the incompressible Navier-Stokes equations in 3-D to model gas flow in a room

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Fredrik Malmström; [2024]
    Nyckelord :;

    Sammanfattning : The thesis proposes to model the flow of gases in a room by solving the incompressible Navier-Stokes equations in three dimensions. The transportationof scalars such as temperature and concentration of CO2 is modeled by solving the advection-diffusion equation, and the effects of temperature on thevelocity is accounted for by employing the Boussinesq approximation.

  3. 2. Control of carbon dioxide capture from biomass CHP plants : Designing a suitable control system to realize the flexible operation of the CO2 capture system

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Tanmmay Rout; [2023]
    Nyckelord :Carbon capture; biomass fired combined heat and power plant; MEA based chemical absorption; flue gas; dynamic operation; PI controllers;

    Sammanfattning : This degree project studies the integration of carbon capture system into biomass fired combined heat and power (bio-CHP) plants. The key disturbances from bio-CHP plants include flue gas flow rate, carbon dioxide (CO2) concentration and available heat for the reboiler because the use of versatile biomass and the dynamic operation of CHP plants results in large fluctuations in the properties of flue gas and the heat input for CO2 capture.

  4. 3. How does different fresh gas flows affect stress in rats during anaesthesia induction with sevoflurane in a chamber?

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Linda Klevestedt; [2023]
    Nyckelord :råtta; beteende; stress; anestesi; inhalationskammare; excitation; induktion; uppvakning; färskgasflöde; sevofluran;

    Sammanfattning : The rat is one of the most used laboratory animals in Europe today. When replacement of live animals in research is not feasible, the aim is to improve the welfare of those animals by reducing stress and suffering. LÄS MER

  5. 4. The effect of nozzle geometry on bubble formation : Physical modeling by air in a water tank

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mhd Osman Bernieh; [2023]
    Nyckelord :Nozzle geometry; bubble formation; water tank model; bubble flow; Munstycksgeometri; bubbelbildning; vattentankmodell; bubbelflöde;

    Sammanfattning : The bubble flow is used for different application in steel production and refining processes. It plays in indispensable role in the ladle refining process such as for homogenization and inclusion removal. Hence, it is important to understand the effect of the nozzle outlet geometry on the bubble formation. LÄS MER

  7. 5. Discharge and Flame Chemistry in Lithium-Ion Battery Vent Gases : Investigations using Breakdown Experiments with Laser-Based Diagnostics

    Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Julia Lövgren; [2023]
    Nyckelord :PLIF; Laser-induced fluorescence; Laser-based diagnostics; Combustion; Lithium-ion battery; Physics and Astronomy;

    Sammanfattning : Due to the environmental impact of fossil fuels, there has been a growing interest in lithium-ion batteries for electric vehicles. However, safety concerns have arisen regarding potential fire hazards associated with the vent gases of these batteries. LÄS MER
