vorticity confinement
Vorticity confinement (VC), a physics-based computational fluid dynamics model analogous to shock capturing methods, was invented by Dr. John Steinhoff, professor at the University of Tennessee Space Institute, in the late 1980s
to solve vortex dominated flows.
It was first formulated to capture concentrated vortices shed from the wings, and later became popular in a wide range of research areas.〔.〕 During the 1990s and 2000s, it became widely used in the field of engineering.〔.〕〔.〕
==The method==
VC has a basic familiarity to solitary wave approach which is extensively used in many condensed matter physics applications.〔.〕 The effect of VC is to capture the small scale features over as few as 2 grid cells as they convect through the flow. The basic idea is similar to that of compression discontinuity in Eulerian shock capturing methods. The internal structure is maintained thin and so the details of the internal structure may not be important.
