1. Evaluation of a stochastic model of coherent turbulent structures for atmospheric particle deposition applications
University essay from Uppsala universitet/Luft-, vatten- och landskapsläraAbstract : In this thesis, we have evaluated a stochastic Lagrangian model for computing particle deposition rates with prospects to use for atmospheric deposition applications. The model is one-dimensional and models the particle dynamics in the boundary layers near walls and obstacles by simulating the coherent turbulent structures and Brownian motion governing the wall-normal transport.

2. 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

3. Predicting Coherent Turbulent Structures with Artificial Neural Networks
University essay from KTH/Matematik (Avd.)Abstract : Turbulent flow is widespread in many applications, such as airplanes or cars. Such flow is characterized by being highly chaotic and impossible to predict far into the future. In turbulent flow, there exist regions that have different properties compared to neighboring flow; these regions are called coherent turbulent structures. READ MORE

4. On the swirl-switching in developing bent pipe flow with direct numerical simulation
University essay from KTH/Numerisk analys, NAAbstract : This work deals with the computational setup, simulation and analysis of turbulent flow through developing bent pipes. Specifically the effect of swirl-switching for the Dean vortices is analysed. A synthetic turbulent inflow condition is implemented and validated. 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
