*********************************** **Pure Species Chemical Potential** *********************************** :: Pure Species Chemical Potential = {model_name} ----------------------- **Description / Usage** ----------------------- This card takes the specification of the standard state chemical potential, which is defined as a function of temperature only, and completes the definition of the pure species chemical potential by possibly adding in a pressure dependence. Two model values are permissible: +--------------------------+-------------------------------------------------------------------------------------+ |**PRESSURE_INDEPENDENCE** |No pressure dependence to the pure species state when this value of {model_name} is | | |specified. The standard state chemical potential is equal to the pure species | | |chemical potential. The argument specifies the species subindex, k. | +--------------------------+-------------------------------------------------------------------------------------+ |**PRESSURE_IDEALGAS** |The following expression holds for the pressure dependence: | | | | | | μk*(T, P) μ= k, o(T) + RTln(P ⁄ 1 atm ) | | | | | | The argument specifies the species subindex, k. | | | | | |The standard state chemical potential, μk, o(T), which is defined to be only a | | |function of the temperature, is used in the evaluation of the definition of the pure | | |species chemical potential of species k, μk*(T, P) , which in turn is used in the | | |evaluation of the mixture chemical potential of species k, μk (T P Xi). | +--------------------------+-------------------------------------------------------------------------------------+ ------------ **Examples** ------------ Following is a sample card: :: Pure Species Chemical Potential = PRESSURE INDEPENDENT 0 ------------------------- **Technical Discussion** ------------------------- The values in this card are only applicable to the *IS_EQUIL_PSEUDORXN* boundary condition currently. -------------- **References** -------------- No References.
