Information
The characteristic radius (R) is the harmonic mean of the (2) principle radii of the liquid volume.
The default surface tension (γ = 0.0663 N/m) is for saturated water at 60 °C, interpolated from [Incropera2002, pp. 924]. Note that the surface tension in [Wang2001] is incorrect (likely unit conversion error).
