    Sammanfattning : The work presented in this thesis focuses on developing methods of measuring moisture properties at high moisture levels. Paper I deal with a new method of measuring moisture diffusivity at high moisture levels. Papers II to IV present methods of measuring moisture storage capacity as well as results from such measurements. LÄS MER

  3. 12. Solute Transport Across Scales : Time Series Analyses of Water Quality Responses to Quantify Retention and Attenuation Mechanisms in Watersheds

    Författare :Joakim Riml; Anders Wörman; Aaron I. Packman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solute transport modeling; Transient storage; Tracer test; Central temporal moments; Spectral analysis; Parameterization;

    Sammanfattning : The intra-continental movement of waterborne contaminants is governed by the distribution of solute load in the landscape along with the characteristics and distribution of the hydrological pathways that transport the solutes. An understanding of the processes affecting the transport and fate of the contaminants is crucial for assessments of solute concentrations and their environmental effect on downstream recipients.

  4. 13. Ion Transport in Cross-linked Nanocellulose Membranes

    Författare :Hongli Yang; Isak Engquist; Magnus Berggren; Klaus-Dieter Kreuer; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membranes; Nanocellulose; Cross-linking; Ion transport; Energy harvesting and storage devices;

    Sammanfattning : Ion-selective membranes, which allow ions with a certain charge and/or size to pass through while blocking other ions, have attracted much attention due to their diverse applications and outstanding roles in overcoming problems related to energy. In addition to the performance, the financial cost and renewability of materials are equally significant in the development of these membranes. LÄS MER

  5. 14. Structural Uncertainties of Rock Fractures and their Effect on Flow and Tracer Transport

    Författare :Martin Stigsson; Vladimir Cvetkovic; Ki-Bok Min; KTH; []
    Nyckelord :Fracture; Flow; Transport; Orientation uncertainty; Roughness; Self-affine; Fractal; Shear; Aperture distribution.; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : Att förstå flöde och transport av lösta ämnen genom sprickorna i berggrunden är viktigt för den långsiktiga säkerheten av ett geologiskt slutförvar av farligt avfall. I en diskret spricknätverksmodell byggs flödesvägarna upp av kedjor av flödesvägar genom de enskilda sprickorna i bergmassan. LÄS MER

  7. 15. Property Impacts on Heat Exchanger Design in CO2 Cryogenic Process of Carbon Capture and Storage

    Författare :Yuting Tan; Jinyue Yan; Hailong Li; Bin Liang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Literature review; CO2 conditioning; CO2 transport; CO2 storage; CO2 mixtures; CO2 cryogenic; heat exchanger; sizing design; property impact; viscosity; thermal conductivity; property model; Energy Technology; Energiteknik;

    Sammanfattning : Carbon capture and storage (CCS) is one of the most promising technologies which can significantly reduce CO2 emissions. A better understanding of thermo-physical properties of CO2 mixtures is required for the design and operation of different CCS processes. LÄS MER
