Class
    Foam::interfaceCompositionModels::Henry
 
Description
    Henry's law for gas solubility in liquid. The concentration of a dissolved
    species in the liquid is proportional to its partial pressure in the gas. A
    dimensionless solubility, \f$k\f$, is given for each species. This is the
    ratio of the concentration of the species in the liquid to the
    corresponding concentration in the gas; i.e., \f$k =
    c_{i,liq}/c_{i,gas}\f$. Mixing in the gas is assumed to be ideal.
