  1. 1. How do metamorphic fluids move through rocks? : An investigation of timescales, infiltration mechanisms and mineralogical controls

    Författare :Barbara I. Kleine; Alasdair D. L. Skelton; John C. Schumacher; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metamorphic fluid flow; fluid-rock interaction; fluid infiltration mechanisms; fluid flux rates; thermodynamic modeling; reaction front propagation; fluid flux calculation; Geology; geologi;

    Sammanfattning : This thesis aims to provide a better understanding of the role of mountain building in the carbon cycle. The amount of CO2 released into the atmosphere due to metamorphic processes is largely unknown. LÄS MER

  3. 2. Development of the Pressure-Time Method for Flow Rate Measurement in Hydropower Plants by Numerical Simulation

    Författare :Simindokht Saemi; Michel Cervantes; Thomas Staubli; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Hydropower is a clean and sustainable energy resource developed since the late 19th century. To specify the hydraulic performance characteristics of hydraulic turbines, the volumetric flow rate as one of the few basic quantities should be determined. Discharge represents the most difficult quantity to measure. LÄS MER

  4. 3. Computational Analysis and Modeling Techniques for Monolithic Membrane Reactors Related to CO2 Free Power Processes

    Författare :Faruk Selimovic; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oxygen Transfer Membrane OTM ; High Temperature Heat Exchanger HTHEX ; Monolithic Heat Exchanger; Advanced Zero Emission Power Plant AZEP ; Mixed Ionic-Electronic Conducting Membranes MIEC ; Computational Fluid Dynamics CFD ;

    Sammanfattning : Funded by European Community and Swiss government research project AZEP (Advanced Zero Emission Power Plant), the project was carried out at the Department of Energy Sciences at Lund Faculty of Engineering (LTH). The project addressed the development of a specific, zero emissions, gas turbine-based, power generation process to reduce local and global emissions in a cost-effective way. LÄS MER

  5. 4. Development of an Impinging Receiver for Solar Dish-Brayton Systems

    Författare :Wujun Wang; Björn Laumert; Torsten Fransson; Torsten Strand; Uwe Gampe; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concentrating solar power; Impinging receiver; Inverse design method; Conjugate heat transfer; High flux solar simulator; Energiteknik; Energy Technology;

    Sammanfattning : A new receiver concept utilizing impinging jet cooling technology has been developed for a small scale solar dish-Brayton system. In a typical impinging receiver design, the jet nozzles are distributed evenly around the cylindrical absorber wall above the solar peak flux region for managing the temperature at an acceptable level.

  7. 5. Mixture Effects in Shell-and-Tube Condensers. Theory and Calculations

    Författare :Tord Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; shell-and-tube; heat transfer; zeotropic; condensation; mass transfer; mixture;

    Sammanfattning : Zeotropic mixtures have come into more frequent use as working fluids (refrigerants) in heat pumps and air conditioning equipment due to the phase-out of ozone-depleting substances. Substantial drop in performance for shell-side condensation in shell-and-tube condensers when replacing a pure fluid with a mixture has been reported in the literature. LÄS MER
