This repository is intended to be shared with the HPC committee of OpenFOAM as an upstream contribution to the community.
The case here is the 3D turbulent flow over a cylinder. Unsteady time-marching Large Eddy Simulation is performed.
The domain size is as followed:
- 38D in radial direction (13D are employed for the non-reflective zone)
- pi*D in span-wise direction
The case consists of a cylinder of unit diameter at the center of the computational domain. The inlet Mach number is 0.2, and the flow properties are such that the Reynolds number is 3900. Three different mesh sizes are provided:
- Small (S): around 1 million total cells
- Medium (M): around 12.5 million total cells
- Large (L): around 80 million total cells
Because of the large size of some of the mesh files, git-lfs was used to store some of the generated polyMesh files.
- The case is setup to run with the solver caaFOAM developed by Prof. Valerio d'Alessandro (Universita Politecnica delle Marche). The link of the solver used with this test case is found here.
- The solver uses an implementation of dynamic Smagorinsky SGS model, that can be found here
Each mesh size contains a run.sh script that untar the heavy mesh files, perform the domain decomposition, renumbering of the mesh, and run of the test case. Just run the script as:
./run.sh X
where X is the desired number of processes.
Data are compared with experimental data of Parnaudeau et. al
