In this study, flowfield and acoustic waves emitted from moving body and rotating elliptic cylinder are directly simulated using the lattice Boltzmann model formulated by the arbitrary Lagrangian Eulerian scheme. The flowfield is almost periodic after the calculation fully developed. Matching procedure between the moving grid and fixed grid is examined. The large vortexes appear at the outside of the elliptic cylinder, and move slowly to the same direction as the cylinder's rotation. The positive and negative vorticity is alternately occurred at the edge by those large vortexes. The acoustic waves propagate synchronizing with the rotational and increase with M<SUP>3.5</SUP> of rotational speed of elliptic cylinder.
