  1. 1. Computational studies of water vapour - Liquid equilibrium

    Författare :Erik Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Monte Carlo simulation; cluster; water; Gibbs ensemble;

    Sammanfattning : It is commonly known that water plays a crucial role in many natural and industrial processes. One of these processes is the formation of water trees, and the subsequent breakdown of polyethylene used for high voltage cable insulation purposes. LÄS MER

  3. 2. Thermodynamic Properties of CO2 Mixtures and Their Applications in Advanced Power Cycles with CO2 Capture Processes

    Författare :Hailong Li; Jinyue Yan; Umberto Desideri; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermodynamic property; vapour liquid equilibrium; density; equation of state; interaction parameter; CO2 mixtures; evaporative gas turbine; chemical absorption; oxy-fuel combustion; cost evaluation; CO2 capture and storage; Chemical engineering; Kemiteknik;

    Sammanfattning : The thermodynamic properties of CO2-mixtures are essential for the design and operation of CO2 Capture and Storage (CCS) systems. A better understanding of the thermodynamic properties of CO2 mixtures could provide a scientific basis to define a proper guideline of CO2 purity and impure components for the CCS processes according to technical, safety and environmental requirements.

  5. 4. Studies of surfactant behaviour and model surfaces relevant to flotation deinking

    Författare :Katarina Theander; Mark Rutland; Krister Holmberg; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : The objective of this work was to investigate the behaviour of some model surfactants used in the deinking process, namely, sodium oleate and two ethoxylated nonionic surfactants (C12E6 and C14E6) as well as to investigate the suitability of various model substrates for mimicking interactions in technical systems. The influence of the adsorption to the air � water interface has been measured by means of equilibrium and dynamic surface tension measurements, as well as foaming experiments. LÄS MER

  7. 5. Numerical Modelling of Diesel Spray Injection, Turbulence Interaction and Combustion

    Författare :Fabian Kärrholm Peng; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atomization; Spray; Flame; Cavitation; Ignition Delay; Lift-off; Combustion; Computational Fluid Dynamics; Numerical Scheme; TVD; Diesel; Turbulence Model;

    Sammanfattning : This thesis covers two main topics. The first is numerical modelling ofcavitating diesel injector flows, focusing on describing suchflows using asingle-phase cavitation model based on a barotropic equation of statetogetherwith a homogenous equilibrium assumption. LÄS MER
