1. 1. Simulation of spillways with the CFD software code_saturne

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Guillaume Coulaud; [2022]
   Keywords : ;

   Abstract : EDF operates 433 hydroelectric facilities throughout France, which must comply with strict safety rules. Spillways are one of the main components of hydraulic structures which ensure their safety in the event of a flood, by releasing flood water. READ MORE

4. 3. Rheology of dense particle suspensions in linear over-damped flow

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Salar Zamani Salimi; [2021]
   Keywords : ;

   Abstract : Suspensions are composed of mixtures of particles and fluid and are omnipresent in natural phenomena and in industrial processes. While hydrodynamic interactions or lubrication forces between the particles are important in the dilute regime, they become of lesser significance when the concentration is increased, and direct particle contacts become dominant in the rheological response of concentrated suspensions, particularly those close to the maximum volume fraction where the suspension ceases to flow.

5. 4. Numerical simulations using Lattice Boltzmann Method

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Mouadh Boubaker; [2021]
   Keywords : Computational fluid mechanics; lattice Boltzmann method; numerical simulations; Beräkningsvätskemekanik; galler Boltzmann -metoden; numeriska simuleringar;

   Abstract : The lattice Boltzmann method (LBM) is widely studied andused in the last years to replace the conventional numerical solvers forthe Navier-Stokes equations. In this work, a general introduction tofluid dynamics equations and the changes when the flow is a reactivemulti-species one will be given first. READ MORE

6. 5. 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
