High Resolution Hybrid RANS/LES Simulations of Flow Over Surface-mounted Cubes Using a Sixth Order Finite Difference Solver

  title={High Resolution Hybrid RANS/LES Simulations of Flow Over Surface-mounted Cubes Using a Sixth Order Finite Difference Solver},
  author={A. Curley and Mesbah Uddin and Brett Peters},
The veracity of two popular turbulence models in predicting highly separated turbulent flows was evaluated in a study of a single surface-mounted cube and two surface-mounted cubes in tandem for various spacings at a Reynolds number of 22,000. Transient hybrid RANS/LES delayed multi-scale simulations using the k−ω SST model and the Langtry-Menter SST transition model were performed using a sixth-order finite difference compressible code OVERFLOW on overset chimera grids generated using Chimera…

Detached eddy simulation of flow around two wall-mounted cubes in tandem
We investigate the performance of unsteady Reynolds-averaged Navier–Stokes (URANS) computation and various versions of detached eddy simulation (DES) in resolving coherent structures in turbulent
Vortex shedding from two surface-mounted cubes in tandem
Abstract Periodic vortex shedding from two surface-mounted cubes, of height H, in tandem arrangement placed in a thin boundary layer is investigated for a spacing 2H using phase-averaged Laser
Turbulent Flow Around Two Interfering Surface-Mounted Cubic Obstacles in Tandem Arrangement
The flow around two in-line surface-mounted cubes in a thin laminar boundary layer was experimentally investigated as a function of obstacle spacing for a Reynolds number of 22,000 based on approach
The flow around a surface-mounted cube in uniform and turbulent streams
An experimental investigation of the flow around surface-mounted cubes in both uniform, irrotational and sheared, turbulent flows is described. The shear flow was a simulated atmospheric boundary
A laser-Doppler velocimetry study of ensemble-averaged characteristics of the turbulent near wake of a square cylinder
Ensemble-averaged statistics at constant phase of the turbulent near-wake flow (Reynolds number ≈ 21400 around a square cylinder have been obtained from two-component laser-Doppler measurements.
The Flow Around Surface-Mounted, Prismatic Obstacles Placed in a Fully Developed Channel Flow (Data Bank Contribution)
The flow field around surface-mounted, prismatic obstacles with different spanwise dimensions was investigated using the crystal violet, oil-film and laser-sheet visualization techniques as well as
