ODTLES: A MULTI-SCALE ANSATZ FOR HIGHLY TURBULENT FLOWS etc15 Tracking Number 431Presentation: Session: Large Eddy Simulation 3 Room: Room E Session start: 10:30 Fri 28 Aug 2015 Christoph Glawe glawechr@tu-cottbus.de Affifliation: Heiko Schmidt schmidth@tu-cottbus.de Affifliation: Alan R. Kerstein alan.kerstein@gmail.com Affifliation: Topics: - Transport and mixing, - Wall bounded flows, - Large eddy simulation and related techniques Abstract: We use ODTLES, a multi-dimensional extension of the One-Dimensional-Turbulence model (ODT). ODT describes turbulent advection on a 1D sub-domain using a stochastic process for turbulent advection. These 1D sub-domains are coupled to obtain a 3D approach. ODTLES is applied to channel flow. Preliminary results for the pdf of the wall shear stress are compared to DNS. |
