Compute Extra Stress van der Waals Gas
Computes a hydrostatic stress corresponding to the pressure of a van der Waals gas that is added as an extra_stress to the stress computed by the constitutive model
Description
The class ComputeExtraStressVDWGas adds an additional hydrostatic stress term, (), to the residual calculation after the constitutive model calculation of the stress, as shown in Eq. (1). This additional hydrostatic stress represents to the pressure exerted by a van der Waals gas.
The diagonal components of the stress tensor are given by (1) where is Boltzmann's constant, is the temperature, is the atomic volume of the lattice atoms in the solid surrounding the gas phase, is the local gas atomic fraction (relative to the surrounding solid), is the van der Waals gas hard-sphere exclusion volume, and for .
