2. Turbulent Shear Flow Experiments: Design of Natural Convection Rig and LDA Measurement in Swirling Jets
Abstract : This work consist of two sections. In the first part, a facility has been installed and modified from an existing rig in order to measure velocity and temperature field of axisymmetric turbulent natural convection boundary layers. With using laser doppler anemometry and cold wire resistance thermometry. READ MORE

3. 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

4. On Gas Turbine Diagnostics with Emphasis on Combustion Chambers
Abstract : The thesis aims to analyse the gas turbine based energy conversion systems with the emphasis on combustion chambers. The investigation is mainly experimental at a component level. The majority of investigations concentrate on gaseous fuel firing. READ MORE

5. Detailed Numerical Simulations of Turbulent Premixed Flames at Moderate and High Karlovitz Numbers
Abstract : In generally accepted and applied flamelet combustion models, a turbulent flame is mainly assumed distorted by the large-scale turbulence eddies, whereas small-scale turbulence effects on the local flamelet structures are neglected. However, in a lot of industrial applications rather high turbulent intensities are often imposed, which induce turbulence scales at ranges smaller than the flame thickness. READ MORE
