Hydraulic Elements

Description

The Linear Hydraulic Resistance block represents a hydraulic resistance where pressure loss is directly proportional to flow rate. This block can be useful at preliminary stages of development, or as a powerful means to speed up the simulation, especially if the flow rate varies insignificantly with respect to the operating point.

Connections A and B are conserving hydraulic ports associated with the block inlet and outlet, respectively.

The block positive direction is from port A to port B. This means that the flow rate is positive if fluid flows from A to B, and the pressure loss is determined as .

Resistance

The linear resistance coefficient. The default value is 10e9 Pa/(m^3/s).

Ports

The block has the following ports:

A

Hydraulic conserving port associated with the resistance inlet.

B
