1. Wind-turbine wake flows - Effects of boundary layers and periodic disturbances
Sammanfattning : The increased fatigue loads and decreased power output of a wind turbine placed in the wake of another turbine is a well-known problem when building new wind-power farms and a subject of intensive research. These problems are caused by the velocity gradients and high turbulence levels present in the wake of a turbine. LÄS MER
2. Formation of Pebble-Pile Planetesimals and the Interior Structure of Comets
Sammanfattning : Planets form in protoplanetary discs of gas, dust and ice around newborn stars. In the Solar System, not only planets are found as a result from the time of planet formation, but also remnant planetesimals in the form of asteroids, Kuiper belt objects and comets. Recent observations, e.g. LÄS MER
3. Adsorption and Mass Transport in Zeolite Membranes
Sammanfattning : Zeolites are commonly used as adsorbents and catalysts in the industry due to their well-defined pores of molecular dimensions. Zeolites offer porous structure, which consists of interlinked alumina and silica tetrahedra with shared oxygen atoms. LÄS MER
4. Synthesis and Applications of Colloidal Zeolites and Transition Metal Functionalized Ordered Mesoporous Carbons
Sammanfattning : Porous materials have attracted a great deal of attention of the materials science community, owing to their physical and chemical properties including high surface areas, narrow pore size distribution, tunable pore diameters and variety of chemical compositions. These properties make them suitable for various applications such as adsorption, sensing, catalysis, energy, carbon capture and drug delivery. LÄS MER
