Description

The Thermodynamic Properties Sensor (G) block represents an ideal sensor that measures specific enthalpy, density, specific heat at constant pressure, and specific entropy in a gas network. There is no mass or energy flow through the sensor.

The block measures these thermodynamic properties at the node connected to port A. The first three measurements (specific enthalpy, density, specific heat at constant pressure) are taken with respect to absolute zero. There is no universal definition of what constitutes zero entropy, therefore you can use the block parameters to provide the reference entropy value for sensor calibration.

Ports

Output

Physical signal output port for measuring the gas specific enthalpy.

Physical signal output port for measuring the gas density.

Physical signal output port for measuring the gas specific heat at constant pressure.

Physical signal output port for measuring the gas specific entropy.

Conserving

Gas conserving port. Connect this port to the node in the gas network where you want to measure the thermodynamic properties. All measurements are taken with respect to absolute zero.

Parameters

The sensor is calibrated so that it outputs this specific entropy value when port A is at reference pressure and temperature.

The sensor is calibrated so that it outputs the value specified by the Specific entropy at reference pressure and temperature parameter when port A is at reference pressure and temperature.
