  2. 1. Well Testing, Methods and Applicability

    Author : Jan-Erik Rosberg; Teknisk geologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slug tests; well completion; re-injection; Well testing; pumping tests; injection tests; well development; pneumatic initiation; hydro-jetting; coiled tubing; tunnel lining; deep wells;

    Abstract : Well testing is widely used today in water wells, oil and gas wells, for geothermal applications, within civil engineering projects, thermal storage and CO2 storage. The overall testing goal is to verify the productivity from a well and/or for characterization of hydraulic and thermal properties, as well as the spatial limitations of an aquifer. READ MORE

  4. 2. Fabrication of Nanostructured Materials for Energy Applications

    Author : Shanghua Li; Mamoun Muhammed; Sanjay Mathur; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materials Chemistry; Materials chemistry; Materialkemi;

    Abstract : World energy crisis has triggered more attention to energy saving and energy conversion systems with high efficiency. There is a growing awareness that nanoscience and nanotechnology can have a profound impact on energy generation, conversion, and recovery. READ MORE

  5. 3. Journal bearing design, lubrication and operation for enhanced performance

    Author : Gregory F Simmons; Rob Dwyer-Joyce; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The increasing introduction of intermittent power sources combined with the de-regulation of electricity markets has led to increased instability in the electrical grid. This has led to increased start-up and shutdown of regulating power sources such as hydro-electric power plants and operation at non-ideal operating states both of which increase the wear and tear on machines.

  6. 4. Experimental and numerical studies of the flow of pulp suspensions

    Author : Julia Claesson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pulp suspension; Laser Doppler Anemometry; Flow behavior; Turbulence; Ultrasound Velocity Profiling; Boundary layer; Local yield stress;

    Abstract : Large amounts of pulp suspensions are handled in the pulp and paper industry daily. In order to produce the final product, paper, a lot of energy is required, e.g. for pumping, mixing and screening the suspensions. READ MORE

  7. 5. An experimental study of the flow of concentrated pulp suspension through a sudden expansion and over a backward facing step
