6. 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

7. Influence of microstructure on debonding at the fiber/matrix interface in fiber-reinforced polymers under tensile loading
Abstract : At the end of the second decade of the XXI century, the transportation industry at large faces several challenges that will shape its evolution in the next decade and beyond. The first such challenge is the increasing public awareness and governmental action on climate change, which are increasing the pressure on the industrial sectors responsible for the greatest share of emissions, the transportation industry being one of them, to reduce their environmental footprint.

8. Investigations of Flow Conditions in an Automotive Wind Tunnel
Abstract : As vehicle manufacturers seek to shorten the development time of new models, wind tunnel testing of prototype vehicles needs to be partially replaced by virtual simulations. However, this requires thorough validation of the virtual methods, which is done by comparison to wind tunnel tests. READ MORE

9. Numerical Investigations of Turbulent Flow in Water Turbines
Abstract : This thesis investigates turbulent flow in water turbines, focusing onthe flow in the vicinity of reaction water turbine runners such as theKaplan runner and the Francis runner. The method of investigationis principally numerical although some experimental observations andmeasurements made in the present work and elsewhere are included. READ MORE

10. Numerical analysis of the single fiber fragmentation test including the effect of interfacial friction
Abstract : A numerical analysis of the single fiber fragmentation test is presented in this thesis. The aim of the numerical study is elucidating the influence of friction in the growth of the debond cracks along the fiber-matrix interface. Two distinct approaches and numerical techniques have been employed in the analysis. READ MORE
