  1. 1. INDUCTIVE RAILWAY SWITCH POINT HEATING : Improved control algorithm and phase compensation analysis for an inductive turnout heating system, and comparison with a resistive heating system

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Erik Nordlund; [2023]
    Keywords : Inductive switch point heating; Turnout heating; railway turnout heating; Inductive heating;

    Abstract : Railway turnout heating is essential during the winter because snow and ice can hinder the movement of the switch. In Sweden, heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance.

  3. 2. Analysis of Heating Processes for the Production of Bipolar Plates in PEM Fuel Cells

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : LASSE MATTHIAS REINPOLD; [2020]
    Keywords : ;

    Abstract : Polymer electrolyte membrane fuel cells (PEMFCs) are a promising alternative to combustion engines and batteries in vehicles. PEMFCs are more efficient than combustion engines, and cars powered by PEMFCs tend to have longer ranges than battery powered cars and has a short fuelling time. READ MORE

  4. 3. Performance analysis of motor for electric aviation

    University essay from

    Author : Torkel Svenson Hagström; [2020]
    Keywords : ;

    Abstract : With a rising interest and improving technology regarding electric aviation, the Swedish ELISE-project aims to built a functional 21-seated electric aircraft by the year 2025. The aim of this thesis is to analyze the performance of a scalable model of an electric motor optimized for aircraft, in terms of magnetic leakage flux, generated back-EMF, torque constant and efficiency.

  5. 4. Thermal design optimization by geometric parameterization of heat sources

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Christoffer Eriksson; [2017]
    Keywords : ;

    Abstract : In this master thesis, a thermal design optimization has been performed. By solvingthe two dimensional steady state conduction convection equation using the finiteelement method in a unit square domain with a source term corresponding tocomponents heated by resistive heating, the objective functional was formulated as aminimization of the combination of a low temperature and small temperaturedifferences inside the domain.

  6. 5. Improvements on HCM Model for g-function Generation and Illustration of Fluid Temperature Prediction

    University essay from KTH/Energiteknik

    Author : Anjan Rao Puttige; [2016]
    Keywords : ;

    Abstract : Ground coupled heat pump (GCHP) is a promising solution to the problem of efficient heating/cooling of residential and commercial buildings. Long term modelling of borehole heat exchanger (BHE) is necessary for better design and operation of GCHP. READ MORE
