An investigation of 3D movement of flows past a circular cylinder
Abstract
Three dimensional (3D) flows past a circular cylinder are computed by a new finite element method based on the choice of upwind and downwind points. In the case of Re = 1,000, the three dimensional structure of the flow is captured; however, in the case of Re = 100, the three dimensionality caused by the tetrahedral subdivision of the domain is dominant and genuine 3D flow movement does not appear.
