  1. 11. Experimental Investigation of Performance, Flow Interactions and Rotor Forcing in Axial Partial Admission Turbines

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Jens Fridh; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; axial turbine; partial admission; part loads; experimental investigation; turbine performance; losses; dynamic rotor forces; forced response; unsteady flow; axialturbin; partialpådrag; dellaster; reglersteg; experimentell undersökning; turbinprestanda; förluster; dynamiska krafter; rotorvibration; instationär strömning;

    Abstract : The thesis comprises a collection of four papers with preceding summary and supplementary appendices. The core investigation solely is of experimental nature although reference and comparisons with numerical models will be addressed. READ MORE

  2. 12. Evaluation of a cyclone gasifier design to be used for biomass fuelled gas turbines

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Hassan Salman; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Abstract : This thesis is a result of experimental studies carried out as a part of the efforts made in Sweden and within the European Union to develop a technology that will make it technically and economically possible to use biomass as a gas turbine fuel. The process that has been studied is based on cyclone gasification of biomass powder and no further cleaning of the product gas from the gasifier. READ MORE

  3. 13. Development and Applications of a General Coupled Thermal-hydraulic/Neutronic Model for the

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Mathias Stålek; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reactor transients; measurements; thermal-hydraulics; core calculations; coupled calculations;

    Abstract : Coupled calculations are important for the simulation of nuclear power plants when there is a strongfeedback between the neutron kineticsand the thermal-hydraulics. A general coupled model of the Ringhals-3 Pressurized Water Reactor has beendeveloped for this purpose. READ MORE

  4. 14. Advanced fuels for thermal spectrum reactors

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Jitka Zakova; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BWR; transmutation; thorium; Pu; MA; Am; Cm; AHTR; thermal; reactor; neutron;

    Abstract : The advanced fuels investigated in this thesis comprise fuels non− conventional in their design/form (TRISO), their composition (high content of plutonium and minor actinides) or their use in a reactor type, in which they have not been used before (e.g. nitride fuel in BWR).

  5. 15. Salvadora persica (MISWAK) : An effective way of killing oral pathogens

    University dissertation from Stockholm : Karolinska Institutet, Department of Odontology

    Author : Abier Hamed Sofrata; Karolinska Institutet.; Karolinska Institutet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Miswak; Salvadora persica; chewing stick; traditional medicine; gingivitis; periodontitis; dental plaque; plaque pH; salivary flow; acid production; microelectrodes; oral hygiene; subgingival microbiota; antibacterial agent; isothiocyanate; chromatography; Porphyromonas gingivalis; Aggregatibacter actinomycetemcomitans;

    Abstract : Mechanical removal of dental plaque is regarded as an effective means of controlling the progression of dental caries and periodontal disease. The habitual use of chewing sticks (Miswak) as an oral hygiene method is still wildly spread throughout parts of Asia, Africa, and the Middle East. READ MORE
