Ideal source of hydraulic energy, characterized by flow rate
The Hydraulic Flow Rate Source block represents an ideal source of hydraulic energy that is powerful enough to maintain specified flow rate at its outlet regardless of the pressure differential across the source. Block connections T and P correspond to the hydraulic inlet and outlet ports, respectively, and connection S represents a control signal port. The flow rate through the source is directly proportional to the signal at the control port S. The entire variety of Simulink® signal sources can be used to generate desired flow rate variation profile.
The block positive direction is from port T to port P. This means that the flow rate is positive if it flows from T to P. The pressure differential is determined as and is negative if pressure at the source outlet is greater than pressure at its inlet. The power generated by the source is negative if the source delivers energy to port P.
The block has the following ports:
