FD-CVC (Feature Detection-Compressible Vorticity Confinement)
methods were introduced by the authors in the past [1] and its result
for some simple problems was investigated. In the present study, FDCVC
methods are used to study vortex flows around bluff bodies such as
projectile and square cylinder. The ability and flexibility of the methods
in more complex and applied problems are studied in this paper. It is
observed that using the FD-CVC methods, by limiting the effect of
vorticity confinement to the points needed, improve the results. It is seen
the proper functioning of these methods on various confinement
parameters (using threshold function) shows the superiority of the
present method over the standard CVC method.
