  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

  2. 2. Predicting the Temporal Dynamics of Turbulent Channels through Deep Learning

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Borrelli Giuseppe; [2021]
    Keywords : Turbulent Flows; Deep Learning; Minimal Channel Flow; Fourier POD FFT-POD ; Data-driven analysis; Long-short-term-memory LSTM networks.;

    Abstract : 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. 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.

  4. 4. LES modelling of spray combustion

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Arvid Åkerblom; [2021]
    Keywords : Gas Turbine; CFD; Large Eddy Simulation; Lagrangian Particle Tracking; Chemical Kinetics; Reaction Mechanism; Combustion; OpenFOAM; CHEMKIN; Technology and Engineering;

    Abstract : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.

  5. 5. 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
