Description

Block Thermodynamic Properties Sensor (TL) It is an ideal sensor that measures the specific internal energy, density and specific heat capacity at constant pressure in the network of a thermal liquid. There are no mass and energy flows through the sensor.

The unit measures these thermodynamic properties in a node connected to port A. All measurements are made relative to absolute zero.

Ports

Output

u — specific internal energy, kJ/kg
scalar

Signal output port for measuring the specific internal energy in the thermal liquid network.

Dependencies

To use this port, check the box for the Internal energy option.

p — density, kg/m^3
scalar

The output port of the signal for measuring the density in the network of a thermal liquid.

Dependencies

To use this port, check the box for the Density parameter.

cp — specific heat capacity at constant pressure, kJ/(kg⋅K)
scalar

The output port of the signal for measuring the specific heat capacity of the coolant at constant pressure.

Dependencies

To use this port, check the box for the Specific heat parameter.

Undirected

A — pass sensor input:q[<br>] thermal liquid

The thermal liquid port corresponds to the entrance to the sensor. Connect this port to the node in the thermal fluid network where you want to measure the thermodynamic properties.

Parameters

Internal energy — enable or disable the output port for measuring specific internal energy
disabled (by default) | enabled

When this check box is set, the output port u is turned on, which allows measuring the specific internal energy of the coolant.

Density — enable or disable the output port for density measurement
enabled (by default) | turned off

When this check box is set, the output port p is turned on, which allows you to measure the density of the coolant.

Specific heat — enable or disable the output port for measuring specific heat capacity
disabled (by default) | enabled

When this check box is set, the output port cp is turned on, which allows you to measure the specific heat capacity of the coolant.
