  2. 1. Aerothermal Experimental Investigation of LPT-OGVs

    Author : Borja Rojo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental; Turbine Rear Structure; Aerodynamics; Wind Tunnel; CFD; Gas Turbine; Engine Exit Structure; Outlet Guide Vane; Heat transfer.; Turbine Exhaust Case; Turbine Rear Frame; Exit Guide Vane;

    Abstract : This thesis presents the design, commissioning, and experimental data of a newly built turbine facility at Chalmers University of Technology for investigating the ow in the engine exit structure (EES). The EES is the structure located downstream of the lowpressure turbine (LPT) in a jet engine. READ MORE

  4. 2. Autonomic reactivity in muscle pain : clinical and experimental assessment

    Author : Nebojsa Kalezic; Eugene Lyskov; Stein Knardahl; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; autonomic reactivity; stress; chronic pain; experimental pain; back; shoulder; neck; Physiology; Fysiologi; Physiology;

    Abstract : There are numerous indications of possible involvement of the autonomic nervous system in the genesis of chronic pain. The possibility exists that sympathetic activation is related to motor dysfunction and changes in sensory processing, which have otherwise been implicated in musculoskeletal disorders. READ MORE

  5. 3. Suffusion of Glacial Till Dam Cores : An Experimental Investigation

    Author : Ingrid Silva; Jan Laue; Peter Viklander; Cristina Jommi; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : Suffusion, also called internal instability, is an internal erosion mechanism that occurs in embankment dams when fine-grained particles are washed out of the core soil matrix by seepage. Initiation of internal erosion depends mainly on three major factors: grain size distribution of the soil, stress conditions and hydraulic load; whilst its continuation depends of the filter properties.

  6. 4. Influence of ice-cover on local scour at circular bridge piers : an experimental study

    Author : Peter Olsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : The objective of this work has been to investigate the effect of a simulated ice cover on the local scour depth around a cylindrical pier. Experiments were performed in a laboratory flume for different flow velocities with both a smooth and rough cover. The bed material consisted of uniform ripple-forming sand. READ MORE

  7. 5. Distribution of Ventilation Air and Heat by Buoyancy Forces inside Buildings : An Experimental Study

    Author : Claes Blomqvist; Mats Sandberg; Per Heiselberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building ventilation; thermal forces; buoyancy; gravity currents; large openings; heating; air quality; forced convection; free convection; Building engineering; Byggnadsteknik;

    Abstract : The main task of the ventilation system in a building is to maintain the air quality and (together with the heating or cooling system) the thermal climate at an acceptable level within the building. This means that a sufficient amount of ventilation air at the appropriate temperature and quality must be supplied to satisfy thermal comfort and air quality demands and that this air is distributed to the parts of the building where people reside.
