In the present study, FDCVCmethods are used to study vortex flows around bluff bodies such asprojectile and square cylinder. The ability and flexibility of the methodsin more complex and applied problems are studied in this paper. It isobserved that using the FD-CVC methods, by limiting the effect ofvorticity confinement to the points needed, improve the results. It is seenthe proper functioning of these methods on various confinementparameters (using threshold function) shows the superiority of thepresent method over the standard CVC method.
