The undulation pump shows excellent performance for pulsatile operation with small size. The pumping effect is produced by precessional waving motion of a disc inside pump housing. In this study, the effect of clearances between the waving disc and pump housing on hydraulic performance was investigated with computational fluid dynamics (CFD) analysis. The result demonstrates that the circumferential clearance had larger influence on the pump performance than the upper and lower clearances because they were more related to the regurgitation flow. This analysis was validated by comparison with the experimental result.
