*GAS SPECIFIC HEAT
Define reacted product's specific heat for an ignition and growth equation of state.

This option is used to specify the specific heat of reacted gas products for an ignition and growth equation of state. It is required when the *EOS, TYPE=IGNITION AND GROWTH option is used. The *GAS SPECIFIC HEAT option should appear immediately after the *EOS or the *REACTION RATE option.

Optional parameter:

DEPENDENCIES

Set this parameter equal to the number of field variables included in the definition of the reacted product's specific heat. If this parameter is omitted, it is assumed that the reacted product's specific heat is constant or depends only on temperature.

Data lines to specify the reacted product's specific heat: 

First line:

  1. Specific heat per unit mass. (Units of JM–1–1.)

  2. Temperature.

  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 specific heat as a function of temperature and other predefined field variables.
