1. Modelling and simulation of turbulence subject to system rotation
Abstract : Simulation and modelling of turbulent flows under influence of streamline curvature and system rotation have been considered. Direct numerical simulations have been performed for fully developed rotating turbulent channel flow using a pseudo-spectral code. The rotation numbers considered are larger than unity. READ MORE

2. Computational dynamics – real and complex
Abstract : The PhD thesis considers four topics in dynamical systems and is based on one paper and three manuscripts.In Paper I we apply methods of interval analysis in order to compute the rigorous enclosure of rotation number. READ MORE

3. Effects of rotation and stratification on magnetic flux concentrations
Abstract : The formation of magnetic flux concentrations in the Sun is still a matter of debate. One observable manifestations of such concentrations is sunspots. READ MORE

4. Combining Models of Coronal Mass Ejections and Solar Dynamos
Abstract : Observations show that Coronal Mass Ejections (CMEs) are associated with twisted magnetic flux configurations. Conventionally, CMEs are modeled by shearing and twisting the footpoints of a certain distribution of magnetic flux at the solar surface and letting it evolve at the surface. READ MORE

5. Analysis of laminar and turbulent flows with turbomachinery, biotechnology and biomechanical applications
Abstract : The goal of this study was initially to gain a better understanding of the effects of rotation on turbulent flow in ducts. Knowledge concerning the influence of rotation on the structures of turbulence is of fundamental importance in many applications, e.g. READ MORE
