  1. 1. Interactive, Effective & Professional Comsol Applications : Based on COMSOL Modules Joule Heating & Corona Discharge

    Kandidat-uppsats,

    Författare :Axel Sigstam; Linus Olofsson; [2023]
    Nyckelord :COMSOL; Hitachi; applications; skin effect; joule heating; corona discharge; townsend;

    Sammanfattning : This thesis will cover how two applications were developed using the commercial software COMSOL Multiphysics. The first application, the Joule heating application, simulates joule heating while taking the skin effect into consideration. The second application, the Corona Discharge application, is used to simulate corona discharges. LÄS MER

  3. 2. Active dielectrophoretic trapping for deterministic single-cell encapsulation in droplet microfluidics

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Prasanna Surana; [2023]
    Nyckelord :negative dielectrophoresis; droplet microfluidics; low conductivity medium; cell viability; COMSOL electric field simulation; joule heating; Rhodamine B temperature measurement; microfluidic chip cleaning; negativ dielektrofores; droppmikrofluidik; medium med låg konduktivitet; cellviabilitet; COMSOL elektrisk fältsimulering; jouleuppvärmning; Rhodamine B temperaturmätning; mikrofluidisk chiprengöring;

    Sammanfattning : The research work focuses on optimizing various parameters for controlling cells using negative dielectrophoresis and entrapping them in droplet microfluidics. This is achieved by developing a conductivity medium, combining CytoRecovery, BSA, and EDTA, to maintain a steady count of single cells with good viability over an extended period. LÄS MER

  4. 3. Evaluation of thermal expansion in busbars used for battery electric vehicles

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

    Författare :FREDRIK LARSSON; [2021]
    Nyckelord :Busbar; Battery electric vehicle; Thermal expansion; Cross-section shape;

    Sammanfattning : Thermal expansion can be an issue in solid busbars, the expansion is caused by several factors and can cause plastic deformation in connection points or structure around it. The expansion occurs due to temperature differences in the busbar as a result of altered ambient temperature and/or joule heating. LÄS MER

  5. 4. Supercoiled Actuators with Liquid Metal Joule Heating : novel miniaturized actuators for pneumatic control of reconfigurable wearables

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik

    Författare :Erik Höijertz; [2020]
    Nyckelord :supercoil; actuator; liquid metal; reconfigurable wearables;

    Sammanfattning : Garments serve a number of purposes, from protection and physiological comfort to social and cultural expressions. With the recent developments of active textiles, sensors and actuators with shapes and sizes similar to textiles, the real multifunctional garments have been realized. LÄS MER

  7. 5. Modelling of battery cooling for Formula Student application : 3D Simulation of air cooled lithium-ion battery with COMSOL Multiphysics®, applied on 2016 years KTH Formula Student car “EV12e”

    Kandidat-uppsats, KTH/Energiteknik

    Författare :Alexander Erik Magnusson; [2016]
    Nyckelord :;

    Sammanfattning : Electric and hybrid cars is one of the technologies to reduce the uses of fossil fuel. What is common with an electric car and a hybrid car is the use of battery to store electrical energy. To sustain high performance, long lifetime and to keep high safety in an electric vehicle it’s very important to control the temperature of the battery cells. LÄS MER
