  1. 1. Elevator evacuation : Exploring behavioural aspects

    Författare :Axel Mossberg; Avdelningen för Brandteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elevator evacuation; evacuation; human behaviour; exit choice; waiting time; occupant evacuation elevator; lift;

    Sammanfattning : As tall buildings and deep underground structures around the world increase in both numbers and complexity, the issues with evacuation of such structures, e.g., fatigue during evacuation or difficulties for people with functional limitations to evacuate, become more prominent.

  3. 2. Multidisciplinary Design in Aeronautics, Enhanced by Simulation-Experiment Synergy

    Författare :Tomas Melin; Arthur Rizzi; Jesper Oppelstrup; Ray Whitford; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aeronautics; conceptual design; design; high lift systems; Vehicle engineering; Farkostteknik;

    Sammanfattning : This thesis covers some aspects of current aircraft design, and presents how experiment and simulation are used as tools. Together they give enhanced effects over employing either one separately. The work presented has been produced using both simulations and experiments. LÄS MER

  4. 3. Experimental study of single fuel jet combustion and high-cycle regenerative systems

    Författare :Simon Lille; KTH; []
    Nyckelord :combustion; preheated air; energy savings;

    Sammanfattning : High Temperature Air Combustion (HTAC) is a technique toreduce consumption of fuel and decrease NOxformation in furnaces. The main change that occursin the furnace chamber is that the flow pattern of flue gasesaltered resulting in a more uniform heat transfer andtemperature profile. LÄS MER

  5. 4. Numerical Analysis of Cavitation-Induced Erosion in High-Pressure Fuel Injectors: under static and dynamic lift conditions

    Författare :Mehmet Özgünoglu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Cavitation Erosion; Fuel Injector; Wobbling;

    Sammanfattning : Fuel injection systems are crucial for all modern combustion engines. These systems often operate under very high pressures to ensure fast spray breakup for optimal fuel air mixing leading to efficient combustion in order to meet strict emission standards. LÄS MER

  7. 5. Compression/Absorption cycles for large heat pumps - Systems simulations

    Författare :Lena Åhlby; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The compression/absorption cycle can, in many situations,give an improved performance compared to the single-fluidcompression heat pump. Also other advantages can beachieved such as the possibility to use an already knownrefrigerant within a new temperature range. LÄS MER
