  1. 1. Characterization of an Electrical Sensor for Combustion Diagnostics

    Författare :Axel Franke; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ion sensor; combustion; nitric oxide; chemi-ionization; equilibrium; Physics; ionized gases; Fysicumarkivet A:2002:Franke; ionization sensor; Fysik;

    Sammanfattning : The ionization sensor is an electrical probe for diagnostics in internal combustion engines. The combustion process affects the electrical properties of the gas in the cylinder. Thus the sensor signal contains copious information about the conditions in the combustion chamber. LÄS MER

  3. 2. Hygroscopic Properties of Aerosols from Open-Air Burning and Controlled Combustion of Biomass

    Författare :Jenny Rissler; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cloud condensation nuclei; H-TDMA; CCN; hygroscopic growth; Teknik; internal and external mixture; CLAIRE; SMOCC; Physics; Fysik; Environmental chemistry; Technological sciences; Miljökemi; tandem differential mobility analyzer; slash and burn; Amazon; Biomass burning; combustion; Fysicumarkivet A:2005:Rissler;

    Sammanfattning : The major uncertainty in predicting the influence of human activities on global climate change is the effect of aerosols. Two physical properties of aerosols largely controlling their influence on climate are the particle number size distribution and the interaction of the particles with the surrounding water vapor.
