1. 1. Deep learning for non-intrusive sensing in turbulence with passive scalars

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Arivazhagan Geetha Balasubramanian; [2021]
   Keywords : Turbulent boundary layer; passive scalar; direct numerical simulation; Prandtl number; Machine learning; convolutional neural network; Turbulent gränsskikt; passiv skalär; direkt numerisk simulering; Prandtl-nummer; maskininlärning; faltningsneurala nätverk;

   Abstract : The near-wall modelling of turbulent flows has been an active field of research due to the computational cost associated with the direct numerical simulations of such flow, which are characterized by a wide range of length and time scales. With the recent advancements in technological capabilities, the availability of high-fidelity data has enabled the construction of data-driven approaches to model turbulence. READ MORE

3. 2. Performance Investigation & Gas Exchange Assessment of Exhaust Piston–assisted Turbocharged Engine (EPTE) Concept : A simulation-based assessment

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Nachiketh Lingachari Acharya; Saurav Dasgupta; [2021]
   Keywords : ;

   Abstract : There is an increasing stringency in the emission legislation within the transport industry along with ambitious performance demands from the customer side. These have pushed the vehicle manufacturers and relevant component suppliers to develop and integrate a wide portfolio of engine technologies. READ MORE

4. 3. Techniques to inject pulsating momentum

   University essay from Luleå tekniska universitet/Strömningslära och experimentell mekanik

   Author : Jelle Kranenbarg; [2020]
   Keywords : Hydro power; Rotating Vortex Rope; Flow control; Fluidic actuator; Synthetic jet actuator; Piston actuator; CFD;

   Abstract : Hydro power plants are an essential part of the infrastructure in Sweden as they stand for a large amount of the produced electricity and are used to regulate supply and demand on the electricity grid. Other renewable energy sources, such as wind and solar power, have become more popular as they contribute to a fossil free society. READ MORE

5. 4. Computational fluid dynamics study of the spillway and plunge pool at Baihetan hydropower station : Numerical validation of the pressure distribution on the floor of an inverted-arch plunge pool

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Anders Ramqvist; Martin Länsmans; [2017]
   Keywords : ;

   Abstract : Large-scale hydropower plants with high discharge flow and spillway heads cause high pressure on the downward plunge pool, resulting in erosion of the riverbed, which could ultimately lead to a dam failure. There is an interest of examining the pressure distribution on the plunge pool floor in order to locate where the pressure peaks most frequently occur. READ MORE

6. 5. The Effects of Erosion-control Structures and Gully Erosion on Groundwater Dynamics Along the Kromrivier, Eastern Cape, South Africa

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Vincent de Haan; [2016]
   Keywords : Gully erosion; wetland; groundwater dynamics; erosion-control structures;

   Abstract : The Palmiet wetlands located along the Kromrivier in the Eastern Cape province of South Africa have experienced severe degradation through gully erosion during the past decennia which has been threatening the water quality and water security of large towns in the Nelson Mandela Metropolitan hub. Water scarcity is a growing problem in this region as a result of land degradation and growing erratic rainfall patterns. READ MORE
