1. Eulerian-Eulerian Modeling of Turbulent Gas-Particle Flow
Sammanfattning : Gas-particle flow is encountered in a vast number of industrial operations and natural phenomena. Computational fluid dynamics plays an important role in practical engineering and fundamental research activities. LÄS MER
2. Fuel Mixing in Gas-Solid Fluidized Beds: A Computational and Experimental Study
Sammanfattning : Fluidized bed technology has been commercially applied over severaldecades. However there is still a lack of knowledge that can provide adetailed understanding of the combustion process in fluidized-bed furnaces. LÄS MER
3. Numerical simulation of thermomechanically coupled transient rolling contact - An arbitrary Lagrangian-Eulerian approach
Sammanfattning : Numerical simulation of rolling contact serves as an important complement to laboratory and full-scale testing in the endeavour to further the understanding of related physical mechanisms, e.g. the influence of friction on the rolling motion, the thermomechanical interaction, damage phenomena and related modes of failure.

4. Numerical Study of Dispersed Two-phase Flows
Sammanfattning : This thesis considers the numerical study of dispersed two-phase flows.Numerical simulations have been done to investigate the particle trasportation/dispersion effect in turbulent two-phase flows. Both turbulent bubble/water flows and turbulent particle/air flows are studied. LÄS MER
5. Numerical Modeling of Turbulent Gas-Particle Flow
Sammanfattning : This work presents a theoretical and numerical study of gas-particle two-phase flow within the Eulerian framework. Although gas-particle flows have been extensively studied, there is still no general agreement on the constitutive equations for an Eulerian-Eulerian model in which the dispersed phase is treated as a continuum, i.e. a granular fluid.
