  1. 1. Humidification Processes in Gas Turbine Cycles

    Författare :Marcus Thern; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Thermal engineering; Energiforskning; Energy research; HAT; Biomass; Biofuel; Humidification; Evaporation; Evaporative gas turbine ; Humid air turbine ; Termisk teknik; termodynamik;

    Sammanfattning : The global climate change caused by emissions of greenhouse gases from combustion processes has been recognized as a continuously growing problem and much research focuses on improving the environmental performance of gas turbines. The potential of improving gas turbine component efficiencies has become smaller each decade and therefore, thermodynamic cycles have become more interesting for power producing units. LÄS MER

  2. 2. Drying of Multicomponent Liquid Films

    Författare :Fabio Luna; KTH; []
    Nyckelord :ternary mixture; falling film; diffusion equation; gas-phase control; liquid-phase control; selectivity; stability analysis; polymeric solution; evaporation; azeotrope; batch drying; continuous drying;

    Sammanfattning : The convective drying of thin layers of multicomponentliquid mixtures into an inert gas, and the influence ofdifferent process controlling mechanisms on drying selectivityis studied. Drying experiments under gas-phase-controlledconditions are performed by low intensity evaporation, fromfree liquid surfaces, of ternary mixtures without non-volatilesolutes. LÄS MER

  3. 3. Advances in droplet evaporation

    Författare :Giandomenico Lupo; Christophe Duwig; Sébastien Tanguy; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Droplet evaporation (and condensation) is one of the most common instances of multiphase flow with phase change, encountered in nature as well as in technical applications. Examples include falling rain drops, fogs and mists, aerosol applications like electronic cigarettes and inhalation drug delivery, and engineering applications like spray combustion, spray wet scrubbing or gas absorption, spray drying, flame spray pyrolysis.

  4. 4. Gas-Phase Protein Structure Under the Computational Microscope : Hydration, Titration, and Temperature

    Författare :Erik Marklund; David van der Spoel; Albert Heck; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; gas phase; proteins; micelles; proton transfer; Grothuss mechanism; kinetics; Physics; Fysik; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Sammanfattning : Although the native environment of the vast majority of proteins is a complex aqueous solution, like the interior of a cell, many analysis methods for assessing chemical and physical properties of biomolecules require the sample to be aerosolized; that is, transferred to the gas-phase. An important example is electrospray-ionization mass spectrometry, which can provide a wide range of information about e. LÄS MER

  5. 5. Experimental investigation of flows related to gas turbine combustion

    Författare :Dragan Stankovic; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; combusiton; flameless; jets in cross flow; chemiluminescence; POD; LIF; PIV; Spray; Gas Turbine; single digit NOx; Premixed Combustion; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Sammanfattning : The notion of "global warming" has become a major public-domain concept as an environmental threat to our future on earth. Independently of the accuracy of existing prediction of combustion emissions on the climate on earth, the concept of reducing combustion emissions has been an important political driving force in imposing more and more severe restrictions on harmful emissions from combustion.
