文摘
The adaptive wavelet collocation method is firstly incorporated into the LBM. Use IBM to eliminate special treatments near the inner boundaries. A grid refinement criterion based on the wavelet amplitudes is used. The grid is refined according to the smoothness of density distribution functions.
