*CAPACITY
Define the molar heat capacity at constant pressure for an ideal gas species.

This option is used to define the molar heat capacity at constant pressure for an ideal gas species. It can be used only in conjunction with the *FLUID BEHAVIOR option.

Required parameter:

TYPE

Set TYPE=POLYNOMIAL to define the molar heat capacity in the form of a polynomial expression.

Set TYPE=TABULAR to define the molar heat capacity in tabular form.

Optional parameter:

DEPENDENCIES

This parameter is relevant only for TYPE=TABULAR. Set this parameter equal to the number of field variables included in the specification of the molar heat capacity at constant pressure. If this parameter is omitted, the molar heat capacity at constant pressure is assumed not to depend on any field variables but may still depend on temperature.

Data line for TYPE=POLYNOMIAL: 

First (and only) line:

  1. , the first molar heat capacity coefficient. (Units of JMOLE–1K–1.)

  2. , the second molar heat capacity coefficient. (Units of JMOLE–1K–2.)

  3. , the third molar heat capacity coefficient. (Units of JMOLE–1K–3.)

  4. , the fourth molar heat capacity coefficient. (Units of JMOLE–1K–4.)

  5. , the fifth molar heat capacity coefficient. (Units of JMOLE–1K.)

Data lines for TYPE=TABULAR: 

First line:

  1. Molar heat capacity, , at constant pressure. (Units of JMOLE–1K–1.)

  2. Temperature, if temperature dependent.

  3. First field variable.

  4. Second field variable.

  5. Etc., up to six field variables.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than six):

  1. Seventh field variable.

  2. Etc., up to eight field variables per line.

Repeat this set of data lines as often as necessary to define the heat capacity at constant pressure as a function of temperature and other predefined field variables.
