17. In the special case of equal superheating (i.e., when Δ T u = Δ T l = 1) the argument of the logarithm in Eq. is multiplied by a factor of 2.
18. / 2 in the present Eq. recovers the corrected version of their Eq. (59) when the different definitions of β are taken into account. Since D now appears only in the corrected version of their Eq. (59) in the combination β / D the solution for β in this case is simply β = 0.7799 D for all values of D. Fortunately, the qualitative conclusions of WDB's stability analysis are not affected by this minor error.
19. - 4) are possible depending on a variety of factors including the local temperature and pressure and whether the free surface is stagnant or dynamically renewing, and so the value α = 1 used here may significantly overestimate the local mass flux.
