In these cases the two modes interact strongly and they achieve first order limit cycles simultaneously. The inherent throttling action and complex 3D flow in control valves result in vibration and intolerable noise at small and medium valve openings. The effects of flow patterns and superficial velocities on the pressure pulsations and vibration responses are evaluated in detail. The reduced velocity within the cylinder array is low and there is no coupling between the adjacent cylinders.
