1. On Efficient Modelling of Wheel-Rail Contact in Vehicle Dynamics Simulation
Sammanfattning : The wheel-rail contact is at the core of all research related to vehicletrackinteraction. This tiny interface governs the dynamic performanceof rail vehicles through the forces it transmits and, like any high stressconcentration zone, it is subjected to serious damage phenomena. LÄS MER
2. Molecular Processes in Dynamic Wetting : Du som saknar dator/datorvana kan kontakta Cathrine Bergh, [email protected] för information
Sammanfattning : The spreading of liquids onto and over surfaces is a fundamental process in nature. It is present in all forms and sizes: From rivers carving through landscapes, to our blood stream transporting nutrients to cells, and even single water molecules moving through channels into these cells.

3. Modelling of Moving Contact Lines in Two-Phase Flows
Sammanfattning : Moving contact line problems appear in many natural and industrial processes. A contact line is formed where the interface between two immiscible fluids meets a solid wall. Examples from everyday life include raindrops falling on a window and water bugs resting on water surfaces. LÄS MER
4. On Heavy-Haul Wheel Damages using Vehicle Dynamics Simulation
Sammanfattning : Maintenance cost is one of the important issues in railway heavy-haul operations. In most of the cases, these costs are majorly referring to reprofiling and changing the wheels of the locomotives and the wagons. The main reason of the wheel damages is usually severe wear and/or surface initiated rolling contact fatigue (RCF). LÄS MER
5. Capillarity and wetting of non-Newtonian droplets
Sammanfattning : Capillarity and dynamic wetting of non-Newtonian fluids are important in many natural and industrial processes, examples cover from a daily phenomenon as splashing of a cup of yogurt to advanced technologies such as additive manufacturing. The applicable non-Newtonian fluids are usually viscoelastic compounds of polymers and solvents. LÄS MER
