Space--Time VMS Computation of Incompressible Flows With Airfoil Geometries and High Reynolds Numbers
A new version of the Deforming-Spatial-Domain/Stabilized Space--Time (DSD/SST) formulation of incompressible flows has been introduced recently to have additional subgrid-scale representation features.

| Summary: | A new version of the Deforming-Spatial-Domain/Stabilized Space--Time (DSD/SST)
formulation of incompressible
flows has been introduced recently to have additional
subgrid-scale representation features. This is the space--time version of the residual-based
variational multiscale (VMS) method. The new version is called DSD/SST-VMST
(i.e. the version with the VMS turbulence model) and also Space--Time VMS
(ST-VMS). The thesis starts with a brief overview of the ST-VMS method. It continues
with a comprehensive set of test computations with 3D airfoil geometries at
high Reynolds numbers and comparison with experimental data. The thesis shows
that the test computations signal a promising future for the ST-VMS method. |
