1. Using GPU-aware message passing to accelerate high-fidelity fluid simulations
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Motivated by the end of Moore’s law, graphics processing units (GPUs) are replacing general-purpose processors as the main source of computational power in emerging supercomputing architectures. A challenge in systems with GPU accelerators is the cost of transferring data between the host memory and the GPU device memory. READ MORE

2. Deep learning for non-intrusive sensing in turbulence with passive scalars
University essay from KTH/Strömningsmekanik och Teknisk AkustikAbstract : 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. Machine Learning Applications To Turbulence
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : By using a fully convolutional neural network, accurate predictions are made of turbulent flows in an open channel. The flow fields were predicted at two different heights y+ = 15,50 in the wall-normal direction. The effect of different input parameters of the neural network have been studied by generating two neural network models. READ MORE

4. The Development of a New High Aspect-Ratio Turbulent Channel Flow Facility
University essay from KTH/Strömningsmekanik och Teknisk AkustikAbstract : Turbulent channel flows are of great interest for investigations of modified wall boundary conditions due to their well-understood characteristics and their broad applicability. In a reversal of typical trends, they can often be more difficult to investigate experimentally than to simulate owing to the far-reaching influence of corner effects as well as the need for development lengths in excess of 200 channel half-heights in order to produce high-quality flow.

5. Turbulent flow control via nature inspired surface modifications
University essay from KTH/MekanikAbstract : Many of the flows in nature are turbulent. To modify turbulent flows, nature serves itself with different types of coatings. Sharks have riblets-like structures on their skin, fishes have slime with polymers and the surface of the lotus flower has superhydrophobic properties. READ MORE
