1. CFD of Air Flow in Hydro Power Generators
Abstract : The air flow through a generator has been numerically investigated with different rotor and stator designs to give a better understanding of the flow for cooling purposes. A simple rotor design has been chosen to start with, and modified through a set of changes, where stepwisemodifications have been imposed to the design of the rotor and the stator. READ MORE

2. Numerical Simulation of Turbulent Flows for Turbine Blade Heat Transfer Applications
Abstract : Turbine blade heat transfer is an important engineering problem characterized by complex flow fields and high turbulence levels. This thesis is focused on using a full Navier-Stokes solver with two-equation eddy-viscosity models to predict external heat-transfer in single-stage, linear, two-dimensional uncooled turbine cascades.

3. Robust Numerical Wall Functions Implemented in OpenFOAM
Abstract : This thesis presents two new numerical wall models for computing Reynolds-Averaged-Navier-Stokes (RANS) equations with low-Reynolds-number turbulence models. Theobjective is to considerably reduce the total central processing unit (CPU) cost of thenumerical simulations of wall bounded flows while maintaining the accuracy of anylow-Reynolds-number turbulence model.

4. Numerical modelling of highly swirling flows in a cylindrical through-flow hydrocyclone
Abstract : Three-dimensional turbulent flow in a cylindrical hydrocyclone is considered and studied by means of computational fluid dynamics using software packages CFX and Fluent. The aim has been to identify the methods that can be used for accurate simulation of the flow in three-dimensional configurations in hydrocyclones at high swirl numbers. READ MORE
