Abstract

Abstract

The application of wavelet method to vortex motion's prediction was investigated.First,the wavelet method was used to solve two initial boundary problems so as to verify its abilities of controlling numerical errors and capturing local structures.Then,the adaptive wavelet method was used to simulate the vortex emerging process.The results show that the wavelet method can predict the vortex evolution precisely and effectively.The application of this method to turbulence is suggested at last.
