1. A Realizable Hybrid Mixture-Bubble Model for Cavitating Flows
Sammanfattning : Cavitating multi-phase flows include an extensive range of cavity structures with different length scales, from micro bubbles to large sheet cavities that may fully cover the surface of a device. To avoid high computational expenses, incompressible transport equation models are considered a practical option for simulation of large scale cavitating flows, normally with limited representation of the small scale vapour structures.

2. 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
3. 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
4. Fluidized Bed Operating Parameters and Eulerian Erosion Models
Sammanfattning : A numerical two-fluid code, Gemini 2D, was adapted to study gas-solid fluidization in arbitrary 2D domains. The code was also used to study fluid dynamic mechanisms of dense particle flow that cause ductile and brittle erosion of solids. LÄS MER
5. Atmospheric & Oceanic Applications of Eulerian and Lagrangian Transport Modelling
Sammanfattning : This thesis presents several ways to understand transports of air and water masses in the atmosphere and ocean, and the transports of energy that they imply. It presents work using various kinds of observations as well as computer simulations of the atmosphere and oceans. LÄS MER
