  1. 1. Numerical Tool for Thermal Analysis of Space Computers

    University essay from Uppsala universitet/Elektricitetslära

    Author : Baran Hamad; [2023]
    Keywords : thermal; space; thermal analysis; thermal design; space computer; heat transfer; PCB; lumped parameter; lumped element; thermal resistance; termisk; rymd; termisk analys; termisk design; rymddator; värmeöverföring; PCB; lumped parameter; lumped element; termisk resistans;

    Abstract : This master thesis addresses the development of an automatic numerical tool for thermal analysis, focusing on thermal systems comprising a printed circuit board assembly and cooling case structure. The project, conducted in collaboration with Unibap, aims to enhance the design process of space computer modules by automating middle steps between design software and thermal analysis results.

  3. 2. Heat-pipes in electric machines : Heat management in electric traction motors

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Anton Olofsson; [2022]
    Keywords : Heat-pipe; Heat pipe; FEM; LPM; Traction motors; Induction motor; Heat management;

    Abstract : The world is continually changing towards more energy efficient alternatives and less pollution. For the traction market, electric powertrains have become the go-to method, superior to both steam and diesel-electric hybrid systems. READ MORE

  4. 3. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Simon Pääjärvi; [2022]
    Keywords : Rotordynamics; Applied Mechanics; Dynamics; Rotor; Finite Element Analysis; Hydropower; Solid Mechanics; Energy Production;

    Abstract : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. READ MORE

  5. 4. Design, simulation, and testing of an electric propulsion cluster frame

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jeremy Bek; [2021]
    Keywords : Electric propulsion; gridded ion thruster; cluster; frame; thermal modelling; mechanical modelling; lumped-parameter model.; Elektrisk framdrivning; jonmotor; kluster; ram; termisk modellering; mekanisk modellering; klumpelementmodell.;

    Abstract : In general, electric propulsion offers very high efficiency but relatively low thrust. To remedy this, several ion engines can be assembled in a clustered configuration and operated in parallel. This requires the careful design of a frame to accommodate the individual propulsion systems. READ MORE

  6. 5. Differential Millimetre Wave On-Chip Inductors

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Francisco Gonzalez Manero; [2019]
    Keywords : Technology and Engineering;

    Abstract : The increasingly interconnected world requires systems that support high data rates, and thus the development of mm-wave systems is necessary. Automotive collision radar (80 GHz) or WLANs (60 GHz) are one of the applications that led the increment of the demand in RFICs, in which monolithic devices are fundamental, such as on-chip inductors or transformers.
