Turbulence Modeling
Turbulence Modeling is at the core of what we do at our Singapore office in BroadTech Engineering.
Featured Turbulence Modeling Case Studies
Objective: The aim of the Turbulence modeling is to set up both computational studies successfully with an appropriate mesh grid refinement, turbulence model, numerical scheme and spatial discretization.
Approach: Reynolds Averaged Navier-Stokes (RANS) and Detached Eddy Simulation (DES) are performed
in a wall-mounted cube in a wind-tunnel domain at Reynolds number 40,000.
Computational cost is limited by 1e6 cells in the 3D domain. Models reliability are tested through velocity profiles, contours, iso-surfaces and streamlines representations compared to experimental results.
Results: Finally, accurate results are obtained by DES, while RANS simulation is unable to capture transient fluctuations related to turbulence structures. Given problem presents several vortex structures well defined that are only well captured by DES.
However, good results in terms of general flow patterns and velocity magnitudes are obtained with Quadratic Upstream Interpolation for Convective Kinematics (QUICK) algorithm discretization
and non-equilibrium wall function for near wall treatment.
