2. 1. The flow of pulp suspensions

   Author : Helena Fock; Chalmers University of Technology; []
   Keywords : Pulp suspensions; Velocity profile; Concentration profile; Wall layer; Particle image velocimetry; Flow behaviour; Computational fluid dynamics; Ultrasound velocity profiling;

   Abstract : Large quantities of pulp suspensions are handled in the pulp and paper industry and knowledge of their flow behaviour is very important in the design and operation of process equipment. Despite this, there is still a lack of a fundamental understanding of the mechanisms of the pulp suspension flow. READ MORE

4. 2. Ultrasound Doppler Based In-Line Rheometry - Development, Validation and Application

   Author : Johan Wiklund; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; Livsmedelsteknik; Technological sciences; non-Newtonian; Chemistry; Kemi; process control; In-line rheometry; Doppler; process monitoring; ultrasound;

   Abstract : The trend within fluid industry is towards continuous production, leading to an increasing demand for new and improved methods that allow real-time monitoring of quality parameters and fast process control. The consistency and viscosity can be described by fluid rheology and are frequently used as quality control parameters. READ MORE

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

   Author : Julia Claesson; Chalmers University of Technology; []
   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

   Author : Julia Claesson; Chalmers University of Technology; []
   Keywords : Ultrasound Velocity Profiling; Laser Doppler Anemometry; Pulp suspension; Flow behavior; sudden expansion; backward facing step;

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