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

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

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

    Sammanfattning : 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. LÄS MER

  3. 2. The Anatomy of the Chua circuit

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Jakob Lavröd; [2014]
    Nyckelord :Chaos; Chua circuit; Lyapunov exponent; Validation; Physics and Astronomy;

    Sammanfattning : The Chua circuit, known to exhibit chaotic behaviour, has been constructed and studied. The goal was to investigate the experimental underpinning of the theory. The component relationship of the resistors, capacitors, inductors and operational amplifiers have been measured and established within their domain of validity. LÄS MER

  4. 3. The chaotic rotation of elongated particles in anoscillating Couette ow

    Master-uppsats, KTH/Mekanik

    Författare :Niclas Berg; [2013]
    Nyckelord :;

    Sammanfattning : Flows with suspended particles occur in a large range of engineering applicationsand biological systems. A fundamental understanding of the uidparticlecoupling can be obtained by analyzing single particles in simple ow situations. LÄS MER

  5. 4. Spreading of wave packets in lattices with correlated disorder

    Magister-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Jakob Rönnbäck; [2011]
    Nyckelord :Markov chain; Correlation Function; Memory Function; Tight-Binding; Lyapunov Exponent;

    Sammanfattning : It is known that a highly ordered medium allows certain wave functions to move unhindered throughout and in this manner achieve delocalization. It is also known that if one introduces disorder into a medium, wave packets will not be able to move as freely and will instead be trapped or localized. LÄS MER

  7. 5. Numerical Study of Polymers in Turbulent Channel Flow

    Master-uppsats, KTH/Mekanik

    Författare :Faranggis Bagheri; [2010]
    Nyckelord :polymer turbulent Lyapunov exponent;

    Sammanfattning : The phenomenon of drag reduction by polymers in turbulent flow has beenstudied over the last 60 years. New insight have been recently gained by meansof numerical simulation of dilute polymer solution at moderate values of theturbulent Reynolds number and elasticity. LÄS MER
