  2. 1. Fibre flow mechanisms

    Author : Roger Bergström; Ulf Björkman; Bo Norman; Mark Martinez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre flow; floc; shear; compression; fibre network; stress chain; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : The flow behaviour, and primarily the floc-floc interaction, of pulp paper suspensions have been studied visually. Analogy models based on these observations have been developed as well as the identification of important parameters of floc break-up in low shear rate flow fields. READ MORE

  4. 2. Fibre-Optic Displacement and Temperature Sensing Using Coupling Based Intensity Modulation and Polarisation Modulation Techniques

    Author : Johan Jason; Hans-Erik Nilsson; Bertil Arvidsson; Werner Daum; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical fibre sensor; displacement measurement; temperature measurement; fibre coupling; intensity modulation; birefringence; polarisation; OTDR; side-hole fibre;

    Abstract : Optical fibre sensors are employed in the measurements of a number of different physical properties or for event detection in safety and security systems. In those environments which suffer from electromagnetic disturbance, in harsh environments where electronics cannot survive and in applications in favour of distributed detection, fibre-optic sensors have found natural areas of use.

  5. 3. Modelling and Validation of Industrial Measurement Systems - Aspects of Quality and Human Factors

    Author : Jenny Wirandi; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uncertainty Analysis; Quality Index; Instrumentation technology; Mät- och instrumenteringsteknik; Traceability; Fuzzy Variable; Pulp Quality; Industrial Measurement; Human Factor; GUM; Calibration; Fibre Measurement; Measurement Science;

    Abstract : Although there is a fairly large number of books and articles concerning the validation of technical measurement systems, there are only a few which take into account the whole measurement system consisting of both technical and non-technical aspects. A measurement system comprises both the measurement process and the human being who conducts the measurement. READ MORE

  6. 4. Flow Field and Fibre Fractionation Studies in Hydrocyclones

    Author : Jonas Bergström; Bo Norman; Mark Martinex; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre suspension; fractionation; hydrocyclone; measurement technique; velocity measurement; shear forces; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Hydrocyclones can be used to fractionate fibres according to their papermaking potential. The obtained fractions typically differ in fibre wall thickness and/or degree of fibre treatment. Despite a multitude of potential application scenarios, the process has so far had little commercial success. READ MORE
