Pl. Vitagliano et al., Experimental tests and numerical simulation of double diffusive convectionin isothermal three component diffusion boundaries, J MOL LIQ, 94(2), 2001, pp. 113-126
A computer code for the unsteady 3-dimensional analysis of convection and d
iffusion has been applied to the three-component system Sucrose(1) - Sodium
chloride(2) - Water.
Numerical results show the evolution of convective motions due to gravitati
onal instabilities that arise as a consequence of diffusion (double diffusi
ve convection), in agreement with theory and experiment.
The evolution of convection was also observed directly and some pictures of
these motions have been reported.
