1. Predicting the Temporal Dynamics of Turbulent Channels through Deep Learning
University essay from KTH/Strömningsmekanik och Teknisk AkustikAbstract : The interest towrds machine learning applied to turbulence has experienced a fast-paced growth in the last years. Thanks to deep-learning algorithms, flow-control stratigies have been designed, as well as tools to model and reproduce the most relevant turbulent features. READ MORE

2. Reduced Order Modelling using Dynamic Mode Decomposition and Koopman Spectral Analysis with Deep Learning
University essay from Lunds universitet/Matematik LTHAbstract : In the industry simulation models are commonly used in system development. These models can become complicated in order to capture the physical behaviour of the underlying dynamical system. A high-fidelity representation, which can result in long simulation times, is in some settings not strictly required. READ MORE

3. Koopman mode analysis of the side-by-side cylinder wake
University essay from KTH/MekanikAbstract : In many situations, fluid flows can exhibit a wide range of temporal and spatial phenomena. It has become common to extract physically important features, called modes, as a first step in the analysis of flows with high complexity. READ MORE

4. Classification of Drill Core Textures for Process Simulation in Geometallurgy : Aitik Mine, Sweden
University essay from Luleå tekniska universitet/Mineralteknik och metallurgiAbstract : This thesis study employs textural classification techniques applied to four different data groups: (1) visible light photography, (2) high-resolution drill core line scan imaging (3) scanning electron microscopy backscattered electron (SEM-BSE) images, and (4) 3D data from X-ray microtomography (μXCT). Eleven textural classes from Aitik ores were identified and characterized. READ MORE

5. Simulation and modal analysis of instability and transition in a steady eccentric stenotic flow.
University essay from KTH/MekanikAbstract : Direct numerical simulation (DNS) of steady flow, with Re = 750 at inlet, through stenosed pipe has been done to study transition and turbulence of the flow in the post-stenosis area. The pipe has 75% constriction by area reduction and 5% eccentricity of the main pipe diameter at the throat. READ MORE
