GAS_FRACTION

Parent

GAS_MIXTURE.CONSTANT

GAS_MIXTURE.VARIABLE

Description

Molar fraction of the specified GAS in the mixture.

Attributes

Attribute	Type	Default	Unit	Description
GAS_NAME	Ref			Ref to GAS. Gas name[1]
MOL_FRACTION	Real			Molar fraction[2]
Notes: 1. GAS_NAME can be a reference to a user-defined gas specified under GAS or a name of one of the predefined gases: 2. Range: [0, 1].

Additional Information

If the molar fractions of the different gases do not sum to 1.0, they are scaled so they do.
Two different c_p formulations can be used for predefined gases by setting CP_FORM under CONTROL_AIRBAG.
When a gas is defined as child of either the parent of INFLATOR_CHAR or INFLATOR_CHAR itself, it can be referenced without a path. See also the example at INFLATOR_CHAR for further information.
