CFD approach

Solvers:

Participants should perform the CFD analysis with updated and validated RANS solvers, either for structured or unstructured meshes, with their best practice. For all the computations, flow medium is ideal gas.

Turbulent Models:

SST model is suggested for the workshop, participants could also select SA or other models according to their experience.

Meshes:

Two sets of multi-block structured grid are provided as the standard workshop grid. One is for geometry AVM and the other is for AVM-DZ. The scale of far field is located 100 x MAC away from the origin of the structural coordinate system in both directions of the Xc and Zc axis, 50x MAC in the span direction from symmetrical plane. The boundary layer mesh contains 45 levels, the height of the first level is about 1.13E-6m, and the growth rate is 1.2. The average Y+ of the grids is around 1.0.

There are two files for each standard grid. One with suffix of “tin” is used to describe the model’s geometry for ANSYS ICEM CFD software and the other  with suffix of “blk” is used to describe grid topology. Mesh files in CGNS format  (about 2 GByte in size) are also prepared. 

Besides the standard grids, the participants are encouraged to generate and apply their own mesh, or both. In this case the medium-sized grid with similar node number to the standard grids is suggested.

The size of the standard AVM grid:

  • Number of zones: 907
  • Number of nodes: 28965948
  • Number of cell: 28599360
  • Number of cell on surface: 732000

The size of the standard AVM-DZ grid:

  • Number of zones: 1195
  • Number of nodes: 40170636
  • Number of cell: 39697408
  • Number of cell on surface: 944832
