SUMMARYIn this paper a finite element version of the direct Laplacian method is applied to flows around an oscillating body, using the arbitrary Langrangim-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 ( . I Fluids Struct., 6, 39-50 (1992)), 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.
