Development of a third-order accurate vorticity confinement scheme
Article dans une revue avec comité de lecture
A new 3rd-order Vorticity Confinement scheme is presented as an extension of the original VC2 scheme developed by Steinhofffor the resolution of the fluid dynamic equations. The theoretical developments are explained, and the method is tested. The results obtained show that the new scheme combines the accuracy of the underlying higher order scheme and the confinement capability of the original VC2 method.

(ELSEVIER, 2017)High-order extensions of the Vorticity Confinement (VC) method are developed for the accurate com- putation of vortical flows, following the VC2 conservative formulation of Steinhoff. First, a high-order formulation of VC ...
