  3. 2. Numerical study of a jet impacting a heated object

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Moutaz Hammoud; [2023]
    Nyckelord :Numerical model; COMSOL Multiphysics; Heat transfer; Impinging jets.;

    Sammanfattning : Heat transfer brought about by impinging jets is common in several industrialapplications such as the cooling of heated objects. The purpose of this investigationis to create a numerical model of an impacting jet, then to use it in parametricresearch and in the cooling of an electronic device. LÄS MER

  4. 3. Inverse source modeling of roll induced magnetic signature

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

    Författare :Erik Thermaenius; [2022]
    Nyckelord :inverse modeling; inverse; modeling; magnetic; signature; source modeling; tikhonov; roll; magnetic silencing; regularization; regularisation; induction; dipole; dipoles; Helmholtz; inversmodellering; magnetisk; signatur; källmodellering; rullning; rullningsinducerad; regularisering; dipol; dipoler;

    Sammanfattning : Vessels constructed in electrically conductive materials give rise to frequency-dependent, induced magnetic fields when waves of water cause them to roll in the Earth's magnetic field. These fields, typically referred to as roll-induced magnetic vortex fields, are a component of the ship's overall signature, where signature refers to measurable quantities which can reveal or identify objects.

  5. 4. Implications of different sensor resolutions and contrast settings in a roll-to-roll process, considering the speed of the process vs identifying defects, for manufacturing green batteries : A study on the effect of light conditions on thedetection of defects in cathode foil in batteries

    Master-uppsats, KTH/Mekatronik

    Författare :Behnam Yosef Nezhad Arya; [2021]
    Nyckelord :Contrast; Surface; Resolution; Speed; Defect; Sensor; Battery; Computer vision; Roll-to-roll; Contact Image Sensor; Mechatronics; Ljusinställning; Yta; Kontrast; Resolution; Hastighet; Defekt; skada; Sensor; Batteri; Computer vision; Roll-to-roll; Contact Image Sensor; Mekatronik.;

    Sammanfattning : This Master’s thesis work is about the conditions that can affect the identification of defects in lithium-ion batteries. In lithium batteries, there are cathode and anode, which are separated with electrically insulative but ionically conductive electrolytes and separators. LÄS MER
