Research on the adaptive wavelet method for the enhancement of computational efficiency of three dimensional flows

Abstract

The adaptive wavelet method is studied for the enhancement of computational efficiency of three-dimensional flows. Three-dimensional wavelet decomposition process is introduced based on the previous two-dimensional method. The order of numerical accuracy of an original solver is preserved by applying a proper thresholding technique. The proposed algorithm is applied to the computation of flow field around ONERA-M6 wing in transonic regime. Through the application, it is confirmed that the three-dimensional adaptive wavelet method can reduce the computational time with conserving the numerical accuracy of an original solver. ? 2012 by the American Institute of Aeronautics and Astronautics, Inc.
