1. 6. Silicon Drift Detector Simulations for Energy-Dispersive X-ray Spectroscopy in Scanning Electron Microscopy

   University essay from Stockholms universitet/Fysikum

   Author : Sebbe Blokhuizen; [2023]
   Keywords : X-ray spectroscopy; Silicon drift detector; Scanning Electron Microscopy; Detector Simulation;

   Abstract : Scanning Electron Microscopy combined with Energy Dispersive X-ray Spectroscopy (SEM-EDS) is a widely applied elemental microanalysis method. The integration of silicon drift detectors (SDDs) has notably enhanced EDS performance, enabling precise elemental identification due to its large sensitive area and low output capacitance.

3. 7. Investigation of charge injection at electrode-dielectric interface relevant for HVDC cables : Simulation of charge injection and transport dynamics in electrical insulation for HVDC cables

   University essay from Uppsala universitet/Tillämpad mekanik

   Author : Mohammed Mosa; [2023]
   Keywords : BCT model; charge injection; space charge density; electric field distribution; Fowler-Nordheim; Richardson-Schottky;

   Abstract : A bipolar charge transport (BCT) model is used to simulate charge injection and transportdynamics inside insulation material which are used in a high voltage direct current (HVDC)cable. Gaining knowledge about space charge density and electric field distribution in theinsulation material enables minimising charge injection at the metal-insulator interface andavoiding unnecessary energy loss.

4. 8. 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

   Abstract : This thesis explores the heat transfer characteristics of a packed bed thermal energy storage device through the development of a 3D model in COMSOL Multiphysics. The model is based on a laboratory-scale device consisting of an aluminum box filled with sand, which acts as the thermal storage medium. READ MORE

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

   University essay from

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

   Abstract : 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. READ MORE
