  1. 1. Particle Measurements Using Fluctuations in the Regular Transmittance of Light Through a Particle Dispersion : Concentration and Particles size - Theory, Measurement Principles and Applications for Pulp and Paper Production

    Författare :Staffan Rydefalk; Lars Mattsson; John Gregory; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particle concentration; Particle size; Cylindrical particles; Large particles; Cellulose fibres; Wood pulp fibres; Suspensions; Particle length; Particle length distribution; Particle width; Manufacturing engineering; Produktionsteknik;

    Sammanfattning : The regular transmittance of light or similar radiation through a flowing suspension of particles fluctuates because of the random occurrence of particles in the beam.In the work presented here, a theory for this fluctuating behaviour with the emphasison dispersions of mm-length slender cylindrical particles having circular crosssections is given.

    Sammanfattning : This thesis is about high energy heavy ion physics. Two major experiments, the WA98 at CERN and the PHENIX at Brookhaven National Laboratory, are described. Results from data analysis from both experiments are presented. The WA98 chapter presents particle identification methods and phi-meson measurements. LÄS MER

  7. 5. On Particle Transport and Turbulence Modification in Air-Particle Flows

    Författare :Camilla Ljus; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; turbulent dispersion; hot film probe; turbulence measurements; turbulence modification; particle transport; two-fluid model;

    Sammanfattning : The transport of particles by airflow was studied for two different flow cases, the transport of pulp fibres in a mat-forming process and the transport of pulp fibres and spherical particles in a horizontal pipe. The transport of pulp fibres in the mat-forming process is first considered. LÄS MER
