1. Global stability analysis of complex fluids
Abstract : The main focus of this work is on the non-Newtonian effects on the inertial instabilities in shear flows. Both inelastic (Carreau) and elastic models (Oldroyd-B and FENE-P) have been employed to examine the main features of the non-Newtonian fluids; shear-thinning, shear-thickening and elasticity.

2. Dynamic properties of two pedestrian timber bridges : Experimental and numerical analysis at several stages of construction
Abstract : Pedestrian bridges can beneficially be made from timber in order for our society to reach a sustainable future. This positive development is partly made possible due to advances in engineered wood products (e.g. glued laminated timber) and the possibilities for pre-fabrication of structural parts. READ MORE

4. Structural-acoustic vibrations in wooden assemblies : Experimental modal analysis and finite element modelling
Abstract : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. READ MORE

5. Modal Analysis of Supersonic Flow Separation in Nozzles
Abstract : Operating a convergent-divergent nozzle under overexpanded conditions can lead to supersonic flow separation in the divergent section of the nozzle. In this case, an attached oblique shock wave forms at the separation base. READ MORE
