Finite element simulation of 3D flow around a circular cylinder

The application of a finite element scheme to full three-dimensional (3D) incompressible viscous flow around a circular cylinder is presented in this paper. The scheme is based on the Petrov-Galerkin weak formulation using exponential weighting functions and on the second-order accurate Adams-Bashforth strategy as a time integration. As a typical example of the problems, flow around a circular cylinder involving an interesting phenomenon of the drag crisis is performed numerically. Numerical results demonstrate the workability and the validity of the present approach.
