21. The Mirroring Immersed Boundary Method - Modeling Fluids with Moving and Interacting Bodies
Sammanfattning : The detailed fluid flow around arbitrary, moving, interacting and deforming bodies is both complex and poorly understood and the commercial simulation tools simulating such flows are computationally to demanding. Hence, a new fast and accurate method for simulating complex multi-body flows is required. LÄS MER
22. Modelling the Production and Propagation of Sound in Individual Human Vocal Tracts
Sammanfattning : Voice generation and the expression through speech are of vital importance for communication. The human upper airways are the origin of the process of speech production, which involves a modulation of the periodically pulsed pressure from the lungs by the vocal tract volume. LÄS MER
23. ON THE WAKE STRUCTURES OF FLOW AROUND DEFORMING AND VIBRATING BODIES
Sammanfattning : This thesis concerns the study of Fluid-Structure interaction phenomena among deforming and (non-deforming) vibrating objects under unsteady fluid fl ow exposures. This multi-physical phenomenon is widely encountered in real-life situations and therefore it is of significant importance to understand the underlying physics. LÄS MER
24. Utilization of Decomposition Techniques for Analyzing and Characterizing Flows
Sammanfattning : This thesis presents the utilization of two different decomposition techniques, proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD), for enhanced understanding of flow structures and their stability. The advantages of these techniques are shown for a range of flow situations, most of which are turbulent. LÄS MER
25. On determining lost core viability in high-pressure die casting using Computational Continuum Mechanics
Sammanfattning : The subject of this thesis work is to investigate whether Computational ContinuumMechanics (CCM) can serve as a valuable tool for the casting engineerto determine a priori whether a housing concept with inlying geometries thatso far only exists in Computer Aided Design (CAD) will have the desired coolingperformance and will be manufacturable with an acceptable number ofrejects.As of spring 2019, no application in serial production of lost cores, i.
