    Sammanfattning : Generating inflow fields for scale-resolving simulations of turbulent flow is crucial for a wide range of applications and is an active area of research. In this thesis, a method for inflow generation employing a precursor turbulent channel flow simulation is proposed. LÄS MER

  2. 2. Modelling Techniques for Large-Eddy Simulation of Wall-Bounded Turbulent Flows

    Författare :Timofey Mukha; Mattias Liefvendahl; Hrvoje Jasak; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Wall modelling; Inflow generation; Large-eddy simulation; OpenFOAM; Computational fluid dynamics; Scientific Computing; Beräkningsvetenskap;

    Sammanfattning : Large-eddy simulation (LES) is a highly accurate turbulence modelling approach in which a wide range of spatial and temporal scales of the flow are resolved. However, LES becomes prohibitively computationally expensive when applied to wall-bounded flows at high Reynolds numbers, which are typical of many industrial applications. LÄS MER
