  1. 26. Capacitive Mixing for Extracting Concentration Gradient Energy

    Författare :Zhi Zou; Longcheng Liu; Chia-Hung Hou; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; capacitive mixing; salinity gradient energy; salt difference energy; electric double layer; flow electrode CapMix; kapacitiv blandning; salthaltsgradientenergi; saltskillnadsenergi; elektriskt dubbelskikt; flödeselektrod CapMix.; Chemical Engineering; Kemiteknik;

    Sammanfattning : Capacitive mixing (CapMix) is a renewable method of extracting energy from the salinity gradient energy (SGE) between seawater and freshwater. The classical CapMix systems using solid electrodes generate electricity by periodically circulating seawater and freshwater into the CapMix system. LÄS MER

  4. 28. Mixing and Stagnation in Drinking Water Storage Tanks

    Författare :Ola Nordblom; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; storage tank; service reservoir; jet mixing; khappa - epsilon model; stagnation; tracer test; temperature measurement; thermal stratification; buoyant jets; CFD model;

    Sammanfattning : This thesis contributes to studies of the assessment of mixing conditions in drinking water storage tanks and analyses of parameters governing mixing rates and formation of stagnant zones. The work also contributes to a validation of Computational Fluid Dynamics (CFD) models of jet-forced mixing in storage tanks under neutral and thermally stratified conditions. LÄS MER

  5. 29. Experimental analysis of thermal mixing at reactor conditions

    Författare :Mattia Bergagio; Henryk Anglart; Paolo Vinai; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mixing estimator; empirical mode decomposition; Hilbert-Huang transform; uncertainty assessment; radial heat flux; Energy Technology; Energiteknik; Fysik; Physics;

    Sammanfattning : High-cycle thermal fatigue arising from turbulent mixing of non-isothermal flows is a key issue associated with the life management and extension of nuclear power plants. The induced thermal loads and damage are not fully understood yet. LÄS MER

  7. 30. Gas Mixing in a Circulating Fluidised Bed Boiler

    Författare :Johan Sternéus; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circulating fluidized bed; gas mixing; tracer; boiler; dispersion; scaling; turbulence; two-phase flow; fluidization;

    Sammanfattning : The present thesis is a study on the gas-mixing behaviour in a circulating fluidised bed (CFB) boiler. The aim is to describe how gas is spread in different regions of a CFB furnace and to explain variations in the mixing rate under different operating conditions. LÄS MER
