A Three-Dimensional Adaptive Wavelet Method for Fluid-Structure Interaction

An adaptive wavelet collocation method for three-dimensional fluid-structure interaction at large Reynolds numbers is presented. This approach is shown to give accurate results with a reduced number of computational elements. The method is applied to two-dimensional flow past moving and fixed cylinders at Re = 102 and Re = 104, and to three-dimensional flow past a sphere at Re = 500. This is the first three-dimensional calculation of a flow past an obstacle using a dynamically adapted wavelet based approach.
