Abstract
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.
