21. Mass conservative network model for convective net flow in a complex urban geometry
University essay from Umeå universitet/Institutionen för fysikAbstract : When simulating air flows in an urban environment, for e.g. pollutant dispersion investigations, today's main tool is advanced computational fluid dynamics simulations. These simulations take a lot of time and resources to perform, even for small geometries. READ MORE

22. Validation and modeling of power losses of NJ406 cylindrical roller bearings
University essay from KTH/Maskinkonstruktion (Inst.)Abstract : I de flesta maskiner används lager för att ta upp krafter från roterande komponenter. I en växellåda används lager för att ge axlarna möjlighet att rotera fritt och att begränsa deras rörlighet i axiell och radiell led. READ MORE

23. A High Order Finite Difference Method for Simulating Earthquake Sequences in a Poroelastic Medium
University essay from Uppsala universitet/Avdelningen för beräkningsvetenskapAbstract : Induced seismicity (earthquakes caused by injection or extraction of fluids in Earth's subsurface) is a major, new hazard in the United States, the Netherlands, and other countries, with vast economic consequences if not properly managed. Addressing this problem requires development of predictive simulations of how fluid-saturated solids containing frictional faults respond to fluid injection/extraction. READ MORE

24. SURFACE DRAG MODELING FOR MILLED SURFACES
University essay from KTH/MekanikAbstract : One of the governing sources of energy loss in a modern day jet engine is attributed to surfacedrag. This energy loss can be divided into friction loss and to surface geometry loss. READ MORE

25. Quantification and Implementation of Structural Damping in MBS Flexible Bodies
University essay from Lunds universitet/MekanikAbstract : In multi body simulation (MBS) using flexible bodies, damping is an important model input to be able to predict the response of a structure with sufficient precision. The purpose of this thesis has been to estimate the structural damping of an experimental setup and implement the estimated damping into MBS-models of the setup. READ MORE
