  3. 3. Time dependent pressure phenomena in hydropower applications

    Författare :Magnus Lövgren; Luleå tekniska universitet; []

    Sammanfattning : Time resolved pressure measurements in hydropower applications are of great interest. Different parts of the machine experience highly transient flows that influence the function and efficiency of the turbine. This thesis addresses different time dependent pressure phenomena. LÄS MER

  4. 4. Experimental Investigation of Velocity Gust in High Pressure Turbines

    Författare :Kai Freudenreich; KTH; []
    Nyckelord :turbomachinery; unsteady aerodynamics; gust; forcing function; forced response; transonic flow; annular cascade; Laser-Two-Focus Anemometer; experiments;

    Sammanfattning : This thesis investigates the unsteady three-dimensional gustfield in high subsonic and transonic turbine stages based onexperimental velocity data. The generation, propagation andinteraction mechanisms of the velocity gust in high pressureturbines are studied. LÄS MER

  5. 5. The effects of posture, airway pressure and anesthesia on regulation of the regional ventilation and perfusion distribution in healthy humans

    Författare :Sven Nyrén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Anesthesia; ALI; ARDS; CPAP; Dual isotope; Mechanical ventilation; Nitric oxide; Nuclear medicine; Prone position; Regional ventilation; Regional perfusion; SPECT;

    Sammanfattning : Gas exchange has been observed to vary with posture in adult respiratory distress syndrome (ARDS) patients. In this thesis, the effect of posture on theregional distribution of ventilation (V) and perfusion (Q) in the lungs under normal breathing with and without continuous positive airway pressure (CPAP) and during general anesthesia with mechanical ventilation was studied.
