Generate time-varying pressure differential
The Controlled Pressure Source (TL) block represents an ideal compressor generating a variable pressure differential across its inlets. The compressor can hold the specified pressure differential regardless of its mass flow rate. No heat exchange occurs between the compressor and the flowing liquid.
Ports A and B represent the compressor inlets. Both ports are thermal liquid conserving ports. The pressure differential is positive when the pressure at inlet B is greater than the pressure at inlet A. The block provides physical signal port P so that you can specify the pressure differential across the compressor inlets.
Use the Variables tab in the block dialog box (or the Variables section in the block Property Inspector) to set the priority and initial target values for the block variables prior to simulation. For more information, see Set Priority and Initial Target for Block Variables.
No heat exchange occurs between the compressor and the flowing liquid.
The pressure differential between the compressor inlets is independent of the mass flow rate through those inlets.
Enter the cross-sectional area of the adjoining pipes. The default
Enter the mean path length the liquid must flow through to go
from inlet A to inlet B. The default value is
The block has the following ports.
|A||Thermal liquid conserving port associated with compressor inlet A|
|B||Thermal liquid conserving port associated with compressor inlet B|
|P||Physical signal port providing the pressure differential between inlets A and B|
