    Sammanfattning : Climate change is no longer imminent but eminent. To combat climate change, effective, efficient and smart energy use is imperative. Thermal energy storage (TES) with phase change materials (PCMs) is one attractive choice to realize this. LÄS MER

  5. 4. Combustion Chemistry Investigation of Liquid and Solid Fuels

    Författare :Åsa Håkansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gasoline; flame; GC MS; heptane; combustion; pyrolysis; kinetics; emissions; wood; RME;

    Sammanfattning : The aim of this work was to study the combustion of liquid and solid fuels with the emphasis on intermediates and products. Depending on the structure and the complexity of the fuel different reactors and methods were used. Small-scale laboratory reactors were built and chemical analysis and evaluation methods were developed. Heptane. LÄS MER

  7. 5. Biodiesel Spray Combustion Modeling Based on a Detailed Chemistry Approach

    Författare :Junfeng Yang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reduction and Validation; Spray Characteristics; Detailed Chemistry; Biodiesel;

    Sammanfattning : Replacing conventional diesel fuels with biodiesel has the potential to drastically reduce engine-out emissions of soot, carbon monoxide, and total unburnt hydrocarbons, at the cost of slightly increased nitrogen oxide emissions. However, to realize the full benefits of using biofuels in this way, there is a need for theoretical models describing their combustion in internal combustion engines. LÄS MER
