21. Some Mathematical Aspects of Thermo and Fluid Dynamics
Abstract : This thesis contains mathematical treatments of three issues in thermo and fluid dynamics: swirling jets and vortex breakdown, Taylor's hypothesis and conjugate heat transfer. The work on swirling jets is focused on the study of the well-posedness of the conically self-similar free-vortex solutions to the Navier--Stokes equations. READ MORE

22. Resonant vortex-pair dynamics and magnetocalorics in magnetic nanostructures
Abstract : This thesis investigates the dynamics of spin vortex pairs in nanopillars andthermal effects in magnetic multilayers with RKKY-like indirect exchange.Spin vortices are being investigated as storage elements for memory applicationsas well as for GHz oscillators and signal processing devices.

23. Development of Vortex Filament Method for Wind Power Aerodynamics
Abstract : Wind power is currently one of the cleanest and widely distributed renewable energy sources serving as an alternative to fossil fuel generated electricity. Exponential growth of wind turbines all around the world makes it apt for different research disciplines. READ MORE

24. Computational studies of passive vortex generators for flow control
Abstract : Many flow cases in fluid dynamics face undesirable flow separation due torising static pressure on wall boundaries. This occurs e.g. due to geometry as ina highly curved turbine inlet duct or e. READ MORE

25. Observations of water vapour in the middle atmosphere
Abstract : Water vapour is the most important greenhouse gas and plays a fundamental role in the climate system and for the chemistry of the Earth's atmosphere. This thesis presents observations of water vapour in the middle atmosphere with a particular focus on the mesosphere. READ MORE
