Gas Properties (G)

Global gas properties for attached circuit

  • Library:
  • Simscape / Foundation Library / Gas / Utilities

Description

The Gas Properties (G) block defines the gas properties that act as global parameters for all the blocks connected to a circuit. The default gas is dry air.

Each topologically distinct gas circuit in a diagram can have a Gas Properties (G) block connected to it. If no Gas Properties (G) block is attached to a circuit, the blocks in this circuit use the gas properties corresponding to the default Gas Properties (G) block parameter values.

The Gas Properties (G) block lets you select between three gas property models: perfect gas, semiperfect gas, and real gas. The three gas property models provide trade-offs between simulation speed and accuracy. They also enable the incremental workflow: you start with a simple model, which requires minimal information about the working gas, and then build upon the model when more detailed gas property data becomes available. The following table lists the information that must be specified for each of the three gas property models.

For semiperfect gas, caloric and transport properties are functions of temperature. You specify them as one-dimensional arrays corresponding to the Temperature vector. For real gas, all properties are functions of temperature and pressure. You specify them as two-dimensional arrays in which the rows correspond to the Temperature vector and the columns correspond to the Pressure vector.

Simulation issues an error when temperature or pressure is out of range:

  • For perfect gas, you specify the minimum and maximum permissible values for pressure and temperature in the Parameters section.

  • For semiperfect gas, the Valid temperature range parameterization parameter gives you an option to define the permissible range of temperatures by using the lowest and highest values of the temperature vector. You have to specify the minimum and maximum permissible values for pressure.

  • For real gas, the Valid pressure-temperature region parameterization parameter gives you an option to define the permissible ranges of pressure and temperature by using the lowest and highest values of the pressure and temperature vectors, respectively. You can also specify a validity matrix for the pressure-temperature value combinations.

Ports

Conserving

expand all

Gas conserving port that connects the block to the gas network. You can connect it to any point on a gas connection line in a block diagram. When you connect the Gas Properties (G) block to a gas line, the software automatically identifies the gas blocks connected to the particular circuit and propagates the gas properties to all the blocks in the circuit.

Physical Properties

Select the gas property model, which defines the level of idealization: perfect gas, semiperfect gas, or real gas. The gas property model determines the set of physical properties and parameters that you can specify for the working gas. For more information, see Gas Property Models.

Universal gas constant divided by the molar mass of the gas.

Compressibility factor that accounts for deviation from the ideal gas law. It is assumed constant during simulation.

Temperature at which the perfect gas properties are specified.

Specific enthalpy of the perfect gas at the reference temperature.

Specific heat capacity of the perfect gas at constant pressure.

Dynamic viscosity of the perfect gas.

Thermal conductivity of the perfect gas.

Vector of gas temperature values, to be used for table lookup of other gas properties.

The block allows easy switching between the gas property models, without having to change the values of the parameters. Although the parameter name is the same for semiperfect and real gas, the values are independent from each other. The block stores them separately. This way, you can have different lookup tables stored within the block for semiperfect and for real gas.

The default value, both for semiperfect and real gas, is [150 : 10 : 200, 250 : 50 : 1000, 1500, 2000] K.

Parameters

Lowest temperature allowed in the gas network. The simulation issues an error when temperature is out of range. For semiperfect or real gas, you have an option to use the lowest and highest values of the temperature vector as the permissible range of temperatures, instead of specifying this parameter.

Highest temperature allowed in the gas network. The simulation issues an error when temperature is out of range. For semiperfect or real gas, you have an option to use the lowest and highest values of the temperature vector as the permissible range of temperatures, instead of specifying this parameter.

Lowest pressure allowed in the gas network. The simulation issues an error when pressure is out of range. For real gas, you have an option to use the lowest and highest values of the pressure vector as the permissible range of pressures, instead of specifying this parameter.

Select how the block specifies the permissible range of temperatures:

  • Range of gas property vectors — Use the lowest and highest values of the Temperature vector in the Physical Properties section.

  • Specified minimum and maximum temperatures — Use the Minimum valid temperature and Maximum valid temperature parameter values.

Select how the block specifies the permissible pressure-temperature region:

  • Range of gas property tables — Use the lowest and highest values of the Temperature vector and the Pressure vector in the Physical Properties section.

  • Specified minimum and maximum values — Use the Minimum valid temperature, Maximum valid temperature, Minimum valid pressure, and Maximum valid pressure parameter values.

  • Validity matrix — Use the Pressure-temperature validity matrix parameter to specify valid pressure-temperature pairs.

A matrix of validity indicators, where the rows correspond to the Temperature vector and the columns correspond to the Pressure vector in the Physical Properties section. Validity indicator is 1 for valid pressure-temperature pairs and -1 for invalid pressure-temperature pairs.

Dependencies

Enabled when the Valid pressure-temperature region parameterization parameter is set to Validity matrix.

Absolute pressure of the environment.

Mach number below which flow reversal occurs. During flow reversal, the energy flow rate at the ports smoothly transitions between the upstream value and the downstream value.
