Class
    Foam::Henry
 
Description
    Henry's law for gas solubiliy in liquid. The concentration of the dissolved
    species in the liquid is proportional to its partial pressure in the gas.
    The dimensionless constant of proportionality between concentrations on
    each side of the interface is \f$k\f$, and is given for each species.
    Mixing in the gas is assumed to be ideal.
