  1. 16. Study of The Effect of Convective Heat Transfer on Cooling of Overhead Line Conductors Based on Wind Tunnel Experimental Results

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

    Author : Wadih Naim; [2018]
    Keywords : heat balance; overhead conductor; convective cooling; dynamic line rating DLR ; värmebalans; luftledare; konvektiv kylning; dynamisk linjestorlek DLR ;

    Abstract : It is important to keep an overhead power line within rated operating conditions. Thus,an accurate prediction of the conductor's thermal and electrical behavior leads to an increasein reliability and eciency. Under DLR operation, the current rating is adjustedbased on ambient weather and solar conditions to allow for dynamic line loading. READ MORE

  3. 17. Analysis on Tyre Wear : Modelling and Simulations

    University essay from KTH/Fordonsdynamik

    Author : Taozhi Wangs; [2017]
    Keywords : Brush model; Tyre wear; Thermal model; Friction model.;

    Abstract : The tyre is an essential part of a road vehicle. It is in the contact between road and tyre that the forces that create the possibility for the driver to control the vehicle are generated. Tyres, however, wear down, which leads to both unhealthy wear particles and disposal of old tyres, both of which are harmful to the environment. READ MORE

  4. 18. Measurement of the convective heat transfer with wind : Developing and testing an Earth Scaled Atmospheric Temperature Sensor

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Philipp Wittmann; [2016]
    Keywords : Wind; ATS; heat transfer; air temperature sensor; atmospheric temperature sensor;

    Abstract :    The HAbitability, Brine Irradiation and Temperature Package (HABIT) instrument of the ExoMars Surface Platform will investigate the present day habitability of Mars at the near surface environment. This instrument includes three Atmospheric Temperature Sensor's (ATS's) which are similar to the ones previously used on the Rover Environmental Monitoring Station (REMS) of the Mars Science Laboratory (MSL) rover, that has now been operating on Mars for more than four years.

  5. 19. Simulation of Gas Channel Temperatures during Transients for SGT-800

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Tobias Johansson; [2016]
    Keywords : Technology and Engineering;

    Abstract : Siemens Industrial Turbomachinery has developed dynamic gas turbine models to compute performance parameters such as temperature, pressure, mass flow and power during transients. Results from the current dynamic model correspond to measured data except for gas channel temperatures that change too fast during transients. READ MORE

  6. 20. Development of a three-dimensionalthermal analysis tool for sounding rockets

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : André Ryman; Andreas Wahlberg; [2014]
    Keywords : Three-dimensional heat transfer; Finite element method; Sounding rocket; Värmeledning; tredimensionellt; Finita elementmetoden; Sondraket; Simulering;

    Abstract : This thesis has been performed in collaboration with the Swedish Space Corporation at the department Science Services. SSC provides services in the areas of spacecraft subsystems, ground stations and sounding rockets to enable governments, companies and research institutes to benefit from space. READ MORE
