4. 3. Numerical Investigations of Turbulent Flow in Water Turbines

   Författare :Håkan Nilsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiblock; Parallel; Visualization; Validation; Verification; Turbine; CFD; Francis; Numerical; Kaplan;

   Sammanfattning : This thesis investigates turbulent flow in water turbines, focusing onthe flow in the vicinity of reaction water turbine runners such as theKaplan runner and the Francis runner. The method of investigationis principally numerical although some experimental observations andmeasurements made in the present work and elsewhere are included. LÄS MER

5. 4. Accuracy and Convergence Studies of the Numerical Solution of Compressible Flow Problems

   Författare :Erik Sterner; Per Lötstedt; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computational fluid dynamics; Navier-Stokes equations; convergence acceleration; preconditioning; semi-implicit; multiblock; multigrid; finite volume method; Numerical Analysis; Numerisk analys;

   Sammanfattning : The numerical solution of compressible flow problems governed by the Navier-Stokes equations is considered. A finite volume method is used for the discretization in space. Different techniques to accelerate the convergence to a steady state are suggested, and the accuracy of the spatial difference operator is analyzed. LÄS MER

7. 5. A Numerical Study of the Fluid Dynamics of Bubbling Fluidized Beds

   Författare :Hans Enwald; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; validation; two-phase solver; multiblock; statistical bubble parameters; parallelization; bed expansion ratio; bubbling fluidized bed; two-fluid model;

   Sammanfattning : The two-fluid model was evaluated as a tool for predicting local flow behaviour in bubbling fluidized beds. A review is given of the two-fluid model approach for simulation of the flow in bubbling fluidized beds. LÄS MER
