  2. 1. Turbulence measurements in fiber suspension flows : experimental methods and results

    Author : Monika Carina Fällman; Fritz Bark; Daniel Söderberg; Fredrik Lundell; Thomas Wikström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid; flow; turbulent; turbulence; paper; pulp; fiber; fibre; suspension; two-phase; experimental; conductivity; micro-probes; passive scalar; ultrasonic; Doppler shift; Fluid mechanics; Strömningsmekanik;

    Abstract : Turbulent mixing is present in many pulp and paper processes. It is a particularly important factor in the design and improvements of the paper machine headbox, influencing the final paper structure. READ MORE

  4. 2. Noise radiation from drill steels : and other experimental investigations in acoustics and fluid mechanics

    Author : Jan-Erik Ögren; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Drill rod noise has become a major noise source in percussive drilling. Generation of flexural waves, which seem to be responsible for most of the noise, is studied in a model with dynamic photoelasticity and in the real drill rod with strain gauge technique. READ MORE

  5. 3. Towards Automation of Non-Destructive Testing of Welds

    Author : Patrik Broberg; Mikael Sjödahl; Anna Runnemalm; Torbjörn Löfqvist; Högskolan Väst; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Welding; non-destructive testing; NDT; Industriell arbetsvetenskap; Industrial engineering; Experimental Mechanics;

    Abstract : All welding processes can give rise to defects that will weaken the joint and can lead to failure of the welded structure. Because of this, non-destructive testing (NDT) of welds have become increasingly important to ensure the structural integrity when the material becomes thinner and stronger and welds become smaller; all to reduce weight in order to save material and reduce emissions due to lighter constructions.

  6. 4. Laminar and turbulent particle laden flows : a numerical and experimental study

    Author : Seyed Hamid Tabaeikazerooni; Luca Brandt; Jeanette Hussong; Raffaella Ocone; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Suspension flow; inertial effect; turbulent duct flow; finite-size particles; Immersed Boundary Method IBM ; Astigmatism Particle Tracking Velocimetry APTV ; Engineering Mechanics; Teknisk mekanik;

    Abstract : Particle laden flows are widespread in nature and in industrial applications. Dust storms, geophysical flows, pharmaceutical processes, fluidized beds and blood flow are only a few examples. Both global and local properties of a particle laden flow may alter significantly in comparison to the corresponding single phase flow. READ MORE

  7. 5. Phosphorus transport and reduction in compact-bed filters : simulations and experiments

    Author : Amir Jourak; Andy George; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Excessive release of phosphorus from the effluent of on-site sanitation facilities to the environment is one source of aquatic pollution. The primary effect of excess phosphorus in the aquatic environment is eutrophication. READ MORE
