1. Turbine Outlet Guide Vane Flows
Sammanfattning : New design goals on modern jet engines often leads to more highly loaded turbines with fewer stages in order to save weight and cost. This gives higher swirl angles into the outlet guide vane (OGV), implying a more difficult aerodynamic design. LÄS MER
2. Air-pocket transport in conjunction with bottom-outlet conduits for dams
Sammanfattning : Undesired air entrainment in bottom outlet conduits of dams may cause pressure transients, leading to conduit vibrations, blowback, discharge pulsation and even cavitation, and jeopardize the operational safety. Due to design limitations or construction costs, it is impossible to create an air free environment in a pressurized pipe. LÄS MER
3. On investigations of patients with lower urinary tract symptoms due to suspected bladder outlet obstruction
Sammanfattning : Lower urinary tract symptoms (LUTS) are caused by a variety of different diseases, including cancer in the urinary tract, overactive bladder (OB) and bladder outlet obstruction (BOO). In order to find the most plausible cause of the patientís LUTS, a number of different investigations have been developed. LÄS MER
4. Modelling calving and sliding of Svalbard outlet glaciers : Spatio-temporal changes and interactions
Sammanfattning : Future sea level rise associated to global warming is one of the greatest societal and environmental challenges of tomorrow. A large part of the contribution comes from glaciers and ice sheets discharging ice and meltwater into the ocean and the recent worldwide increase is worrying. LÄS MER
5. Modelling air―water flows in bottom outlets of dams
Sammanfattning : If air is entrained in a bottom outlet of a dam in an uncontrolled way, the resulting air pockets may cause problems such as blowback, blowout and loss of discharge capacity. In order to provide guidance for bottom outlet design and operation, this study examines how governing parameters affect air entrainment, air-pocket transport and de-aeration and the surrounding flow structure in pipe flows.
