11. Heat-transfer simulations applied to electrical machines
Abstract : Electrification and energy efficiency are two important aspects in present scenarios describing a sustainable future. Electric motors constitute a large fractionof industry’s electricity demand today, and it is expected to remain high inthe future. READ MORE

12. Numerical study of interface dynamics and phase change
Abstract : Multi-phase fluid flows are ubiquitous in natural phenomena and different industrial applications such as in food industry, the medical sector, heat exchangers, power generation systems, to name a few. Understanding the underlining physics of multi-phase flows proved to be a challenging task due to presence of sophisticated dynamics, including the evolution of the interface between any pair of phases, thermodynamics and possibility of phase change, interactions between the fluid phases and a solid phase, etc. READ MORE

13. Studies on adverse-pressure-gradient turbulent boundary layers on wings
Abstract : The present licentiate thesis addresses the use of well-resolved simulations to simulate turbulent boundary layers (TBL) subjected to adverse pressure gradients. Within the thesis a wide variety of analyses are performed, and a method to improve the performance of the simulations is presented. READ MORE

14. Rapid wetting - influence of surface geometry and fluid properties
Abstract : Wetting of a liquid on a solid surface is ubiquitous in everyday life, such as morning dew on a plant leaf and raindrops hitting on a glass window. However, this phenomenon is far away from being completely understood. READ MORE

15. Transport and mixing by finite-size particles in turbulent flows
Abstract : Suspensions of solid particles in a viscous fluid are ubiquitous in natural and engineering settings, including sediment transport in river beds, blood flow in the human body, oil products transport in pipelines and pulp fibers in papermaking. Multiphase flows consisting of finite-size particles is a challenging topic due to multi-way coupling and interactions between the phases. READ MORE
