An approximation method for the simulation of unsteady flows around moving objects using static Cartesian mesh was introduced. Approximation treatment was introduced at the moving boundary under the small-displacement assumption. Numerical results suggest that the static-mesh/dynamic-boundary method is able to reflect the dynamic characteristics of the moving object.
