An Eulerian numerical scheme for the direct simulation of bubble dynamics in an acoustic field is proposed. The compressible Navier-Stokes equation with a surface tension term is used as a governing equation. The convection terms in the equation are solved using the hybrid interpolation-extrapolation scheme which stably provides a nonsmoothed solution of density interface between bubbles and a surrounding material. The acoustic terms in the equation are solved by the generalized Crank-Nicholson method which is an implicit method and has a temporally second-order accuracy under the low-Courant-number condition and is applicable to high-Courant-number computation. Using this scheme, some typical results of single- and multibubble phenomena are given.
