In simultaneous heat and mass transfer in binary mixtures, mean mass transfer coefficients can likewise be found using the equations from the previous sections. Once again this requires that the mean Nusselt number Num is replaced by the mean Sherwood number Shm, and instead of the Grashof number a modified Grashof number is introduced, in which the density p(p,T, ) is developed into a Taylor series,...

From measurements of the local heat transfer from heated vertical surfaces to cryogens in the natural convection regime, it appears that the laminar boundary layer flow undergoes a transition to turbulence when the modified Grashof number (Gr ) is of the order of 10. This agrees with experiments performed with water. For a heat flux of 100 W/m, the wall boundary layer can be expected to be turbulent above a liquid height of 0.3 m in LNG, with an increase in heat transfer coefficient for wall/liquid heat transfer [ 1 ].
