RISA Parametric Study of Turbulent Flow Past a Circular Cylinder Using Large Eddy Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow over a circular cylinder at a Reynolds number of 3900 is investigated using large eddy simulations (LES) to assess the affect of four numerical parameters on the resulting flowfield. These parameters are subgrid scale ...
Numerical Investigation of Vortex Ring Ground Plane Interactions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The interaction between multiple laminar thin vortex rings and solid surfaces was studied numerically so as to investigate flow patterns associated with near-wall flow structures. In this study, the vortex–wall interaction ...
Investigation of the Flow Structures in Supersonic Free and Impinging Jet Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical study of compressible jet flows is carried out using Reynolds averaged Navier–Stokes (RANS) turbulence models such as kة› and kد‰SST. An experimental investigation is performed concurrently using highspeed ...
Applying Machine Learnt Explicit Algebraic Stress and Scalar Flux Models to a Fundamental Trailing Edge Slot
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Machine learning was applied to large-eddy simulation (LES) data to develop nonlinear turbulence stress and heat flux closures with increased prediction accuracy for trailing-edge cooling slot cases. The LES data were ...
