2. 1. 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

   Abstract : Acoustic fatigue can occur in structural elements of an aircraft exposed to very high sound pressures. To deal with acoustic fatigue, mainly empirical methods have been applied and often late in the design phase. Current design guidelines have three main limitations. First, they do not say anything about the load intensities. READ MORE

5. 3. 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

6. 4. Development of Numerical Methods for Turbulent Flow in Complex Rotating Systems

   Author : Peter Hedberg; Chalmers University of Technology; []
   Keywords : fluid mechanics; computer code; rotating geometries; turbomachinery;

   Abstract : A computer code has been developed to predict three-dimensional incompressible turbulent flow in complex rotating geometries. The application in mind is turbomachinery in general. However such a code is able to treat a large number of problems in fluid mechanics. READ MORE
