Example Grid Family for the BeVERLI Hill (45 Degree Orientation Shown)
Systematic Family of Structured Grids for 30 Degree Hill
NOTE: The following *.zip files contain:
- Native Pointwise (*.pw)
- Plot3d (*.x)
- CGNS Unstructured (*.cgns)
Grid Files for 30 Degree As-Designed BeVERLI Hill (grids in meters)
Grid Files for 300 Degree As-Built BeVERLI Hill (grids in meters)
NOTE: Since these grid files are large, they are hosted on Google Drive. If your organization
cannot access Google Drive, email me and I will make the following Microsoft OneDrive files available:
Geometry Files for Nominal 30 Degree Hill
- Note that as-designed/as-built refers to the Hill geometry only
- The wind tunnel walls in all cases are an idealized tunnel geometry that is:
- Made up of 4 planar walls defined by:
y = 0m, y = +1.85m, z = -0.925m, and z = +0.925m
- Extended upstream to x = -6m as planar walls so
as to match integral boundary layer properties given in the BC info
- Extended downstream to x = +5.5m as planar walls
so as to avoid the complex flow in the diffuser (which has vortex generators to maintain attached flow)
30 Degree As-Designed BeVERLI Hill
*NOTE: The Solidworks and Step files have the hill at 0 degree
orientation and need to be rotated to 30 degrees for the as-designed geometry.
300 Degree As-Built BeVERLI Hill
*NOTE: The Solidworks and Step files have the hill at 0 degree
orientation and need to be rotated to 300 degrees for the as-designed geometry, which was necessary to properly align the LDV windows.
