Abstract
We have extended the CIP (Cubic Interpolated Pseudo-particle) method to the FEM (Finite-Element method) in our previous works. The previous verifcations of GSMAC-CIP scheme were, however, done by using the orthogonal meshes and we don't make use of the characteristic of the FEM. In the present work, GSMAC-CIP scheme is applied to the flow around a circuler cylinder and employs arbirary meshes. That flow is a famous problem which has been studied by many investigators. Therefore, good numerical and experimental data, for example the experimental data obtained by Bouard and Coutanceu, are available easily. The Reynolds numbers are Re=550, 3 000 and 9 500. The numerical results are compared with the experimental data obtained by Bouard and Coutanceu, and the effetiveness of the present scheme is shown. Moreover, we point out the mistakes of their experimental data for the velocity profile on the center axis behind a cylinder at Re=9 500.
