PD Pump Settings Panel

If a PD pump is the source of pulsation, the PD Pump Settings panel is required to calculate the pump flow forcing function which is used in the Pump Speed child scenarios.

The required pump properties are as follows:

• Minimum Pump Speed - affects the lower range of pump speeds at user-selected frequencies after the model has been run.

• Bore - diameter of PD pump bore

• Stroke - pump stroke length

• Rod Length - connecting rod length of pump slider crank

• Clearance - clearance ratio of cylinder expressed in volume units or percent of swept volume (dead volume/swept volume), also often referred to as Dead Volume in literature

• Suction Pressure - average suction pressure

• Discharge Pressure - average discharge pressure
