The numerical codes based on the artificial compressibility method and the unstructured grid were applied to the design of the artificial heart, from the viewpoint of the biomedical engineering. In the present paper, the three-dimensional and unsteady flow in the casing of the vibrating flow pump (VFP), which can generate the oscillated flow and can be applied to the left ventricular assist device, was numerically analyzed. The calculations were based on the geometry and the flow conditions of the prototype device used in the animal tests. The qualitative comparisons of the results between the present analysis and the previous axisymmetric one were made in detail, and the useful suggestions for future research were presented.
