Numerical analysis of 2D vortex‐induced oscillations of a circular cylinder

A finite element version of the direct Laplacian method is applied to flows around an oscillating body, using the arbitrary Langrangian-Eulerian (ALE) formulation for the partial domain around the body. This numerical calculation has been successfully conducted for vortex-induced cross-flow oscillations of a circular cylinder under the same conditions as for Anagnostopoulos and Bearman's experiment, in which the Reynolds number ranged between 90 and 150, a regime where the vortex street is fully laminar. The numerical calculation results have been compared with the experimental data in order to check the calculational accuracy.
