Pressure Source (TL)

Ideal compressor that generates a constant pressure differential across its inlets

Library

Thermal Liquid/Sources

Description

The Pressure Source (TL) block represents an ideal compressor generating a constant 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.

Assumptions and Limitations

  • 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.

Dialog Box and Parameters

Pressure differential

Enter the pressure difference between compressor inlets A and B. The default value is 0 Pa.

Characteristic longitudinal length

Enter the mean path length the liquid must flow through to go from inlet A to inlet B. The default value is 1e-1 m.

Pipe cross-sectional area

Enter the cross-sectional area of the adjoining pipes. The default value is 1e-2 m^2.

Ports

The block has two thermal liquid conserving ports, A and B.
