Definition

A non-uniform pressure is assumed inside the volume. The gas flow in FVMBAG1 is solved using a finite volume integration scheme.

Perfect gas law and adiabatic conditions are assumed. Injected mass, velocity and temperature are defined as a time function. The injected velocity is obtained using the following equation:

Where, S is the injector surface.

A sensor may define the inflator starting time.

Deflation of vent hole is available after reaching a pressure (Pdef) or time (tdef) criteria.

In this version, heat gas capacity Cp is assumed constant.
