  1. 1. Advanced power cycles with mixture as the working fluid

    Detta är en avhandling från Stockholm : Kemiteknik

    Författare :Maria Jonsson; KTH.; [2003]
    Nyckelord :power cycle; mixture working fluid; Kalina cycle; ammonia-water mixture; reciprocating internal combustion engine; bottoming cycle; gas turbine; evaporative gas turbine; air-water mixture; exergy;

    Sammanfattning : The world demand for electrical power increasescontinuously, requiring efficient and low-cost methods forpower generation. This thesis investigates two advanced powercycles with mixtures as the working fluid: the Kalina cycle,alternatively called the ammonia-water cycle, and theevaporative gas turbine cycle. LÄS MER

    Sammanfattning : Water or steam is added into the working fluid (often air) in gas turbines to improve the performance of gas turbine cycles. A typical application is the humidified gas turbine that has the potential to give high efficiencies, high specific power output, low emissions and low specific investment. LÄS MER

  4. 4. CFD MODELLING AND EXPERIMENTS ON AERATOR FLOW IN CHUTE SPILLWAYS

    Sammanfattning : A chute spillway is a typical component of large dams for discharging floods. Because of the high water head, the flow velocity in the chute is often in excess of 20 m/s. Consequently, the structure is usually prone to cavitation damages. Flow aeration is evidenced to efficiently eliminate or to mitigate the damages. LÄS MER

  5. 5. Cereal Proteins. Interfacial and Physicochemical Properties

    Detta är en avhandling från Food Technology, Lund University

    Författare :Lars Wannerberger; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; monolayer; Langmuir-Blodgett deposition; interaction; interfacial properties; adsorption; secalin; Wheat proteins; gliadin;

    Sammanfattning : The main theme of this thesis is the interfacial properties of cereal proteins from wheat and rye. Some aspects of dough bulk properties are also included. The proteins studied are of interest for the stabilisation of gas cells and the mechanism of gas retention, and the rheological properties of a bread dough. LÄS MER
