7.6.4.2.15. From_Bubble_State

Syntax: Density [{of} SpeciesName] = From_Bubble_State Gas_Species_Name = gas_species_name
Scope: Aria Material
Summary: Density from foam bubble model
Description: $\rho = \frac{\mathit{MW}_g * c_g}{\phi}$

where $\mathit{MW}_g$ is the molecular weight of the specified gas species, $c_g$ is its concentration, and $\phi$ is the volume fraction of gas.
