1. A numerical study of two-fluid models for dispersed two-phase flow
Sammanfattning : In this thesis the two-fluid (Eulerian/Eulerian) formulation for dispersed two-phase flow is considered. Closure laws are needed for this type of models. We investigate both empirically based relations, which we refer to as a nongranular model, and relations obtained from kinetic theory of dense gases, which we refer to as a granular model. LÄS MER

3. Simulation of consolidation processes by eulerian two-fluid models
Sammanfattning : The objective of this report is to study a model of agravity and shear induced consolidation process of a dense,flocculated suspension.The suspension is modeled as a two-constituent mixture of afluid and solid particles by an Eulerian two-phase fluid model. LÄS MER
4. CFD MODELLING AND EXPERIMENTS ON AERATOR FLOW IN CHUTE SPILLWAYS
Sammanfattning : A chute spillway is a typical component of large dams for discharging floods. Because of the high water head, the flow velocity in the chute is often in excess of 20 m/s. Consequently, the structure is usually prone to cavitation damages. Flow aeration is evidenced to efficiently eliminate or to mitigate the damages. LÄS MER
