11. Numerical study of flows related to aerated stirred tanks
Sammanfattning : The overall purpose with this work is to investigate the bubbly flow in a aerated stirred tank using numerical simulations. Aerated stirred tanks are commonly used in chemical processes for producing for example insulin and antibiotics. LÄS MER
12. Numerical computations of wind turbine wakes
Sammanfattning : Numerical simulations of the Navier-Stokes equations are performed to achieve a better understanding of the behaviour of wakes generated by wind turbines. The simulations are performed by combining the in-house developed computer code EllipSys3D with the actuator line and disc methodologies. LÄS MER
13. Surface chemistry aspects on adsorption from a multicomponent model metalworking fluid
Sammanfattning : .... LÄS MER
14. Internal erosion in embankment dams : fluid flow through and deformation of porous media
Sammanfattning : A basic understanding of fluid flow through a porous media facilitates a comprehensive understanding of internal erosion in embankment dams. Hence, it is necessary to reveal the detailed seepage flow, the flow-induced forces acting within the porous media and the fluid flow deformation of the porous media. LÄS MER
15. Model predictions of turbulent gas-particle shear flows
Sammanfattning : A turbulent two-phase flow model using kinetic theory of granularflows for the particle phase is developed and implmented in afinite element code. The model can be used for engineeringapplications. However, in this thesis it is used to investigateturbulent gas-particle flows through numerical simulations. LÄS MER
