Modelling the pulsatile flow rate and pressure response of a roller-type peristaltic pump

The unique working mechanics of roller-type peristaltic pumps have allowed their applications to span a wide variety sectors and industries. pump's accurate dosing hydrostatic capabilities can theoretically allow for the pump be used hydraulic actuation (as an electro-hydrostatic actuator) low pressure applications. This however requires control its flow rate. associated pulsations will also impact on selection criteria. Accurate commonly rely flow-meters, which increases cost complicate strategies. Current modelling approaches either do not first principle require expensive simulation software, or apply larger Reynolds numbers at rates. most applicable model focusses rate each roller individually. implies that alterations in order accommodate with varying rollers. paper presents alternative methodology towards volume rate, pulsatile qualities, found pumps. instead inlet outlet pump, rather than individual roller. is highly scalable allows number validated using 3D printed test bench. capable accommodating housings rollers (3 2) validate model.
