  2. 11. Thermal Modelling of Small Cage Induction Motors

    Author : Gunnar Kylander; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal network; thermal model; losses; TEFC; induction motor;

    Abstract : The loadability of electric machines is above all determined by temperature limits. In this work, thermal network models, suitable for totally enclosed fan cooled (TEFC) induction motors, are used to predict the machine temperatures. READ MORE

  4. 12. Analysis of thermal shock in brittle materials

    Author : Marianne Collin; KTH; []
    Keywords : thermal shock; thermal stress; stress intensity; vickers indentation; alumina; silicon varbide whisker reinforced alumina;

    Abstract : This thesis concerns thermal shock damage of ceramicmaterials. More specifically the work is focused on theoreticaland practical aspects of a new technique for determining thethermal shock resistance of brittle materials. READ MORE

  5. 13. Thermal Barrier Coatings : Durability Assessment and Life Prediction

    Author : Robert Eriksson; Sten Johansson; Michael Schütze; Linköpings universitet; []
    Keywords : ;

    Abstract : Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. READ MORE

  6. 14. Thermal response test : numerical simulations and analyses

    Author : Anna-Maria Gustafsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

    Abstract : When constructing large borehole heat exchanger (BHE) systems, bedrock and borehole thermal properties are vital for a good design. Today's design programs presume conductive heat transfer in both borehole and bedrock. READ MORE

  7. 15. Thermal response test : method development and evaluation

    Author : Signhild Gehlin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : Since the first introduction of thermal response tests with mobile measurement devices in Sweden and USA in 1995, the method has developed and spread in North America and Europe. Thermal response tests have so far been used primarily for in situ determination of design data for BHE (borehole heat exchanger) systems, but also for evaluation of grout material, heat exchanger types and groundwater effects.
