Abstract
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.
